I don’t think squash should be a thing we only eat in the fall. It’s a year-round ingredient in our home. We make spaghetti squash chicken alfredo all the time and my new obsession is acorn squash casserole for the holidays.

The caramelized onion as the base of the stuffed squash filling is worth every second of cook time. Just like in french onion chicken, it deepens the flavors and balances out the sweet apples and crispy pork.

  • Ideal fall meal with cozy flavors.
  • Filling without being heavy.
  • Healthy and full of veggies (even spinach!).
  • Goes from main dish to side dish easily.
  • Perfectly balanced with sweet and savory flavors.

  • Acorn squash They’re in the grocery store all year, but you can get them at a local farm too.
  • Onion: caramelizing it adds depth and sweetness like in these cheesy scalloped potatoes.
  • Apples: Cube them small and use Pink Lady or Honeycrisp apples. I love to cook with them and use them in this sheet pan butternut squash, sausage, and apples recipe.
  • Sausage: pork or chicken sausage works and you can buy it or make your own (see recipe notes).
  • Spinach: swap for kale if needed, it wilts just as well, like in this whole30 zuppa toscana.
  • Fresh herbs: sage, rosemary and thyme make all the difference.

Recipe Variations

  • Butternut squash halves: stuff the filling inside butternut squash halves. Bake the squash for 50 minutes instead of 35 for acorn squash.
  • Add rice or quinoa: use leftover rice, quinoa, or farro to mix with the filling.
  • Add cheese: sprinkle parmesan cheese after you fill the acorn squash and melt in the last few minutes of roasting.
  • Nuts and cranberries: stir toasted pecans and dried cranberries into the filling for added texture.
  • Vegetarian stuffed acorn squash: Swap the ground pork for white beans or vegan sausage.

Vegetables: add a vegetable side dish to increase the nutritional variety and fiber. Roasted root vegetables, roasted broccoli and carrots, or air fryer asparagus are great options.

Salad: A big, fresh salad like brussels sprout salad or kale apple salad have fall flavors to balance the stuffed squash.

Soup: serve the squash as a side with a savory soup like lentil sausage soup, healthy chicken soup, panera autumn squash soup, or white bean vegetarian chili.

Ingredients

Instructions 

  • Preheat the oven to 400 degrees and line a baking sheet with parchment paper.

  • While the squash is roasting, make the filling. Heat the oil in a large skillet over medium-low heat. Add the sliced onion and cook for 20 minutes to caramelize the onions, stirring every 2-3 minutes. When the onions are caramelized, add the garlic and cook for 1-2 more minutes.
    2 Tablespoons olive oil or coconut oil, 1 large yellow onion, 3 cloves garlic
  • Add the sausage to the onions and turn the heat up to medium. Season with salt and pepper to taste then cook the sausage for 6-8 minutes, stirring often to break it up until no pink remails.

    1 large apple, 1 tablespoon fresh chopped rosemary, 1 tablespoon fresh chopped sage, 2 teaspoons fresh chopped thyme, 2 cups spinach

Notes

Caramelized onion: thinly sliced onion will cook faster. Keep a close eye on it as you’re cooking so they don’t burn.
Chopping and prep: I like to chop and prep the garlic, apples, and spinach while the onions are caramelizing to save time.
Storage: Store leftovers in an airtight container for up to 3 days. 
Reheat: add a bit of water in the bottom of a baking dish, tent with foil, and bake at 350 until heated through, 15-20 minutes.
Freeze: store leftover and cooled squash in a freezer bag and remove as much air as possible. Store in the freezer for up to 3 months. Thaw overnight and reheat.
Meal prep: make the filling up to 3 days in advance. Follow the instructions to roast the squash, stuff, and serve.
