  • 1/2 c. chopped sweet pepper
  • 1 medium onion (chopped)
  • 1 c. sour cream

  4. Transfer the mixture to a baking dish.
  5. Bake for 30 minutes or until heated through and bubbly.

Tips & Substitutions

For a creamier texture, consider substituting Greek yogurt for the sour cream. You can also use frozen squash if fresh isn't available; just make sure to drain excess moisture. Adding a pinch of nutmeg can elevate the flavor profile. If you prefer a vegetarian option, swap the cream of chicken soup for tarragon cream of chicken soup. Be sure to taste the mixture before baking to adjust seasoning.

Serving Suggestions

This squash casserole pairs beautifully with honey bear chicken for a comforting meal. Serve alongside a fresh garden salad or crusty bread to round out the meal. It also makes a great side for grilled meats or as part of a potluck spread. Consider garnishing with fresh herbs like parsley for added color and flavor.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, preheat the oven to 350°F and bake for about 15-20 minutes until heated through. Alternatively, you can microwave individual portions for a quick meal, but the oven method helps maintain the casserole's texture.
