Ingredients Needed

For the Roasted Squash Base:
  • 2 medium acorn squash (about 1.5 lbs each), halved lengthwise and seeded
  • 1 tablespoon olive oil
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon freshly cracked black pepper
For the High-Protein Pot Pie Filling:
  • 1 pound cooked skinless chicken breast, shredded or finely diced
  • 1 tablespoon unsalted butter
  • 1 small yellow onion, finely diced
  • 2 medium carrots, peeled and diced (about 3/4 cup)
  • 2 ribs celery, finely diced (about 1/2 cup)
  • 2 cloves garlic, minced
  • 1/2 cup low-sodium chicken broth
  • 1/2 cup plain non-fat Greek yogurt (at room temperature)
  • 1/2 cup frozen green peas
  • 1 teaspoon fresh thyme leaves (or 1/2 tsp dried thyme)
  • 1/2 teaspoon dried sage
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 2 tablespoons shredded Parmesan cheese (for optional golden topping)

Step-by-Step Instructions

  1. Roast the Acorn Squash: Preheat your oven to 400°F (200°C). Trim a tiny slice off the rounded back of each squash half if needed so they sit flat. Brush the flesh with olive oil and season evenly with 1/2 teaspoon salt and 1/4 teaspoon pepper. Place flesh-side down on a parchment-lined baking sheet. Roast for 30 to 35 minutes until the flesh is fork-tender and lightly golden on the edges.
  2. Sauté the Aromatic Veggies: While the squash roasts, melt butter in a large skillet over medium heat. Add diced onion, carrots, and celery. Cook for 6 to 8 minutes, stirring occasionally, until vegetables soften and onions turn translucent. Add minced garlic and cook for 1 minute until fragrant.
  3. Build the Creamy Sauce: Pour chicken broth into the skillet to deglaze, scraping up any browned bits. Reduce heat to low. Stir in the Greek yogurt until smooth and fully integrated with the warm broth.
  4. Fold in Chicken and Herbs: Add shredded cooked chicken breast, frozen peas, thyme, sage, salt, and black pepper. Stir well over low heat for 2 to 3 minutes until everything is warmed through and evenly coated in the rich, creamy sauce. Remove from heat.
  5. Stuff and Broil: Flip the roasted acorn squash halves flesh-side up. Divide the chicken pot pie filling evenly among the four cavity centers. Sprinkle top with shredded Parmesan cheese if using. Return to oven and broil on HIGH for 2 to 3 minutes until cheese is melted and bubbling. Garnish with additional fresh thyme before serving.

Pro Tips for Best Results

  • Prevent Yogurt Curdling: Make sure your Greek yogurt is near room temperature before adding it to the skillet, and always drop the pan heat to LOW. Stirring yogurt into boiling broth can cause separation.
  • Use Pre-Cooked Poultry: Rotisserie chicken breast or leftover poached chicken saves considerable time. If you enjoy batch cooking chicken, check out our Crispy Air Fryer Chicken Bites for another easy protein option.
  • Stabilize Your Squash: Slice a small, flat sliver off the bottom outer skin of each acorn squash half before roasting so they do not tip over on your baking sheet or dinner plate.

Storage, Meal Prep & Reheating

  • Refrigeration: Store leftover stuffed squash halves in air-tight glass containers in the refrigerator for up to 4 days.
  • Reheating in Oven/Air Fryer: Reheat in a 350°F (175°C) oven or toaster oven for 12–15 minutes until warm throughout. Alternatively, air fry at 350°F for 8–10 minutes.
  • Microwave Reheating: Microwave individual halves on medium-high power for 2 to 2.5 minutes. Note that squash skin will soften further in the microwave.
  • Freezing: Freezing whole assembled stuffed squash is not recommended due to texture changes in Greek yogurt and squash moisture upon thawing. You may, however, freeze the cooked filling separately in an airtight bag for up to 2 months.

Frequently Asked Questions

Can I eat the skin of acorn squash?

Yes, acorn squash skin is completely edible and becomes quite tender when roasted. However, many people prefer to scoop out the sweet flesh along with the filling and leave the outer peel behind.

Can I substitute butternut squash or spaghetti squash?

Absolutely. Delicata squash, carnival squash, or small butternut squash halves work seamlessly as replacement edible bowls with similar roasting times.

How do I keep the pot pie filling thick without flour?

Thick plain Greek yogurt combined with reduced broth creates a naturally thick sauce. Allowing the sauce to gently simmer before removing from heat naturally tightens the texture without cornstarch or wheat flour.

Is this recipe suitable for work lunch prep?

Yes, it packs and transports exceptionally well in hard glass lunch containers. Reheat in your workplace microwave for a hot, satisfying, high-protein lunch.
