Healthy Butternut Squash Casserole with Sausage and Sage Breadcrumbs

I harbor romantic notions of myself as a farm girl. I’d gather fresh eggs every morning, milk my goats and make cheese in the afternoon, then cook cozy dinners like Butternut Squash Casserole with Sausage, Kale, and Sage Breadcrumbs, using ingredients picked from my land of course.

Butternut Squash Casserole with SausageIn farm girl reality, I’d whine about ruining my shoes in the chicken coop and provoke a goat bite. I still, however, hold fast to the beautiful notion of cooking from what the earth provides right where I am, right now—even if I pick from the grocery store bin, instead of my backyard.

This concept of seasonal eating became real to me when I first started cooking for myself. Directly out of college and on a budget, I quickly realized that seasonal ingredients both cost lest than out-of-season ones and taste much better too. What began as a logical budgetary decision has turned into a passion, and I now look forward to the way the colors in my grocery cart change as the year progresses.

Butternut Squash Casserole with Crumb ToppingMy farm girl alter ego came into being after reading Animal Vegetable Miracle by Barbara Kingsolver. Though Kingsolver has written some of my favorite fictional works, Animal Vegetable Miracle is the true story of how she and her family moved to an inherited farm in Appalachia and ate only what they could grow themselves or buy within 100 miles for a full year. It’s an enthralling read and inspired this self-proclaimed city girl to dream about country life. Two days ago, I asked Ben if he ever thought it would be neat to live on a farm. He responded with an emphatic NO. My suede booties were relieved, but in my defense, Ben hasn’t read the book.

Healthy Butternut Squash Casserole with Chicken SausageThough I’m certainly not a seasonal-eating purist (last February, I bought a $6 pint of raspberries just to remember what summer tastes like), dishes such as this Butternut Squash Casserole with Sausage and Kale remind me that even chilly winter offers ingredients to celebrate. The sweet butternut squash and hearty kale, together with spicy-sweet sausage and rosemary create a vibrant casserole filling so tasty, I snacked on it by the light of my refrigerator door.

Healthy Butternut Squash Casserole with Sausage and KaleThough the butternut squash casserole filling is lovely on its own, it is the breadcrumb topping that makes this recipe something special. I was inspired by a butternut squash crumble recipe in David Lebovtiz’ latest cookbook My Paris Kitchen. David’s version is intended to be a side dish and is rather decadent, but I was so captivated by the idea of a savory (vs. dessert) crumble, I had to try my own version.

I transformed the original side into an all-in-one main dish by adding chicken sausage and kale, shortened the ingredient list to make it more accessible on a weeknight, and adapted the herbs to suit what I had on hand. David’s ingenious cornmeal, breadcrumb, Parmesan, and sage topping, however, had to stay.

Butternut Squash Casserole with Cornmeal ToppingI lightened up the topping by swapping some of the butter for Pompeian Extra Virgin Olive Oil and used whole wheat breadcrumbs. It still turned out perfectly golden and rich—no one will ever notice the healthy substitution.

I can’t say enough wonderful things about this butternut squash casserole. The filling is hearty and flavorful, and the topping is a delightful combination of sweet, salty, cheesy, crunchy. It can be prepped ahead and then baked in the evening, and it tastes fantastic leftover too. This butternut squash casserole is also loaded with veggies and lean protein. You’ll feel like a super star for eating comforting food that’s good for you too.

In addition to the butternut squash and kale in today’s casserole, December has a wealth of other bright offerings. Once again, I’m joining my friend Becky of The Vintage Mixer and the #EatSeasonal blogger team to share a collection of seasonal recipes. We do this each month and would love to have you join us by posting a photo of your own seasonal dishes with the hashtag #eatseasonal. It’s a fantastic way to share December’s best eats, and we’ll regram our favorites too!

#EatSeasonal DecemberI might not be ready for the farm life, but I’m thinking a goat might still make a decent pet. If the neighbors ask questions, I’ll just take them over a big pan of Butternut Squash Casserole with Sausage and Kale (and maybe some cheese). I’m sure there’s no misunderstanding we can’t resolve over plates of comfort food.

Butternut Squash Casserole with Sausage, Kale, and Sage Breadcrumbs

A healthy casserole with butternut squash, chicken sausage, and kale, topped with a golden sage breadcrumb topping. This flavorful recipe is sure to be a family favorite!

Yield: Serves 6

Prep Time: 20 minutes

Total Time: 1 hour 45 minutes


For the Butternut Squash and Sausage Filling

  • 3 tablespoons Pompeian Extra Virgin Olive Oil, divided
  • 1 pound chicken or turkey sausage, casings removed
  • 3-pound butternut squash, peeled, seeded and diced into 3/4-inch cubes
  • 1 tablespoon mined fresh rosemary
  • 1 teaspoon minced garlic (about 2 cloves)
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 12 ounces kale, Swiss chard, or other hearty leafy green, tough stems removed and torn into bite-sized pieces
  • 1/2 cup thinly sliced yellow onion (about 1/2 large)
  • 1 cup low sodium chicken stock

For the Crumble Topping

  • 3 slices whole wheat bread (or 3/4 cup breadcrumbs)
  • 1/2 cup stone ground cornmeal or polenta
  • 1/2 cup freshly grated Parmesan cheese
  • 1 tablespoon minced fresh sage
  • 1 teaspoon granulated sugar
  • 1/2 teaspoon kosher salt
  • 2 tablespoons Pompeian Extra Virgin Olive Oil
  • 2 tablespoons cold unsalted butter, cut into small cubes
  • 1 large egg


  1. Preheat the oven to 375 degrees F. Generously grease a shallow 3-quart baking dish with softened butter or cooking spray.
  2. Prepare the squash and sausage filling: Heat 1 tablespoon of the olive oil in a large, deep skillet or Dutch oven over medium heat. Brown and crumble the sausage until fully cooked, about 5 minutes. Remove from the pan and set aside. Being careful not to burn yourself, wipe out the pan with a paper towel.
  3. Cook the butternut squash filling in two batches (this will ensure the ingredients brown properly): Heat 1 tablespoon olive oil in the skillet, then add half of each of the following: the squash, rosemary, salt, and pepper. Sauté until the squash is beginning to brown, then add half of: the kale, the onions, and the garlic. Cook until the kale and onions begin to soften, about 4 minutes. Add the 1/2 cup of the chicken stock, stir, and let cook 1 minute so that the stock reduces slightly. Stir in half of the reserved sausage. Transfer the mixture to the prepared baking dish and press into a relatively even layer.
  4. Heat the remaining tablespoon olive oil in the skillet, then repeat the above step with the remaining half of each of the ingredients. Transfer the rest of the filling to the casserole dish. Cover the dish with aluminum foil and bake for 30 minutes or until the squash is soft when pierced with a sharp knife.
  5. While the squash bakes, prepare the topping: Place the slices of bread in the bowl of a food processor and pulse into crumbs (if using ready-made breadcrumbs, simply add them to the food processor without pulsing). Add the cornmeal, Parmesan, sage, sugar, and salt. Plus a few times to combine. Drizzle in the olive oil, add the butter cubes, and pulse until crumbly and the butter is fully incorporated. Add the egg and pulse a few additional times, until the mixture just begins to clump together. (Alternatively, you can make in a mixing bowl, cutting in the butter by hand. In this case, you will need prepared breadcrumbs).
  6. Remove the casserole from the oven, take off the foil, then sprinkle the top evenly with the breadcrumb mixture. Reduce the oven temperature to 350 degrees F, return the dish to the oven, then bake uncovered, until the bread crumbs are golden, about 20 minutes. Serve warm.

  1. Such a beautiful dish Erin! Can’t wait to try out the recipe. Sharing and pinning!

  2. I love this casserole. It is filled with healthy, delicious ingredients.

  3. Ahhhh I was a farm girl many many decades ago! I was born and raised on a farm until high school and it was amazing. Just like your dreams… except goats are not really friendly most times! This casserole is amazing. I have all the ingredients right now to put it together :)

  4. Your note about goats reminds me of Darien Gee’s The Avalon Ladies’ Scrapbooking Society. The book opens with some funny goat episodes. Friendship Bread is the first book in this series. I think you’d get a kick out of these books.

    Your recipe sounds amazing! I’ll have to try it, but I won’t tell my Italian husband that it has turkey or chicken sausage in it, lol.

  5. Umm just yes to this entire dish. I am such a fan of butternut squash and this is such a creative way to use it. And healthy? Sign me up!

  6. I have David’s recipe tagged in the cookbook, but this is MUCH simpler, especially on a cold weeknight– thanks, Erin!

  7. If you want to get your fix, come on over to my families farm in New Hampshire. I’m sure my mom would be happy to have you!! And no animals, just plant. So no poop to step in or things to bite you!!

    I’m the exact same way. I love the idea of housing my own chickens, but I’d just complain about getting up before dawn and cleaning the chicken coop. Oh well, maybe we should just live NEXT to a farm and become friends with the farmers.

  9. My mouth started watering about halfway through reading this post. Butternut squash and sage are a match made in casserole heaven. The whole breadcrumb / cornmeal / parmesan topping sounds epic, too. (I don’t think David Lebovits has ever steered me wrong.) I’m pretty sure you could put that on just about anything and make it a million times better!

  10. what a delicious seasonal dish! I try my best to eat seasonally, but I do love my berries

  11. This casserole looks like the perfect seasonal dinner. You’ve combined two of my favorites, butternut squash and kale, and that breadcrumb topping looks crazy good!

  12. Mmmm that topping! I’ve been toying around with the idea of a savory crumble for a while now, and I think you’ve convinced me to get with it. Looks SO good Erin!

  13. This casserole looks so healthy and delicious!! Love all the flavors that are going on!

  14. Yes, Erin, yes! I’d totally join in on those farm-girl fantasies.. and do you read mynameisyeh? She makes my daydreams so much worse. But, like you, my reality would be less than pleasant and I know I’d be whining alllllll the day long. And that’s a super long day starting at like 4:30 a.m.! This recipe, however, pulls together just as much wholesome goodness as a long day on the farm, and no ruining of shoes required :)

  15. Such a great idea to make a savory crumble… I love the flavors in this too! And Barbara Kingsolver is one of my favorite authors of all time :)

  16. Ah. I once had romantic notions about living on a farm.
    And now that I’m living it, it isn’t quite so romantic. :)

  17. Erin, I love butternut squash! And I love that you paired it with some crispy crumb topping! Yumm…

  18. haha, I think about the same things when thinking about farm life. . it would be great but messy :P love this casserole and love the golden sage breadcrumb topping!

  19. Just recently stumbled upon your blog (via Pinterest, I think) and really enjoy the little narratives that go with each recipe! ^^ I actually have a butternut squash and some chard on hand, so I think I’m going to have to attempt an ‘inspired-by’ version of this recipe with substitutions for what I lack. :D You really got me thinking with the ‘seasonal shopping/cooking’ idea… It seems basic and obvious (fresher, less expensive, like you said), but I guess I’m a bit slow to have caught on! Hehe… Time to research! Thanks for all the great ideas and inspiration! ^-^

    • Hi Angie! I’m so happy that you found my blog. Welcome!! This recipe would be fantastic with chard, and a great way to eat seasonally too :) If you try it, I’d love to hear what you think! Have a wonderful night, and thanks for saying hi.

  20. Oh my gosh, these bread crumbs look so good! The cornmeal is such a fantastic addition!

  21. Mmmmm I’m such a fan of seasonal eating as well… I can’t even think about buying a strawberry right now. And those breadcrumbs… LOVE!

  22. Love that you’re channelling your inner farm girl :) You should do this more often if it means recipes like this! All of my favorite ingredients are in this dish!

  23. haha my sister used to want to live on a farm … and now she lives in NYC and is pretty much the ultimate city person!

    Love the sound of this casserole – especially that crumble topping!

  24. I just love this! I have some butternut squash and it is destined to be made into this beautiful casserole!

  25. I’m going to have to make this one when Jim isn’t watching….chicken or turkey sausage isn’t something he would usually eat. I’ll sneak it in there and see if he notices, lol. ;-)

  26. Made this last night and it was great, except for the cornmeal in the topping. Didn’t care for that at all, and I’d leave it out next time. Otherwise, it was excellent for a one-dish meal!
