Description

A hearty Southwestern-inspired yellow squash casserole featuring sautéed veggies, green chiles, corn, cheese, and a crumbled cornbread base. Creamy, savory, and full of flavor—perfect for using up leftover cornbread!


Ingredients

Scale
  • 4 cups chopped yellow squash (about 3 small or 2 medium)
  • 2 tablespoons butter
  • ½ medium onion, chopped
  • ½ cup chopped red or green bell peppers
  • 8 oz white mushrooms, sliced
  • ¼ teaspoon cumin
  • 1 tablespoon all-purpose flour
  • 1 cup milk (whole, low-fat, or evaporated)
  • 1 cup frozen corn
  • 4 oz chopped green chiles (adjust to taste)
  • 1 cup crumbled leftover cornbread or boxed stuffing mix
  • 1 cup shredded cheddar or Monterey Jack cheese
  • Salt and freshly ground black pepper, to taste

Instructions

  1. Cook the Squash: Microwave the chopped yellow squash with 1 tbsp water, covered, for 8–9 minutes. Mash and drain well to remove excess moisture.
  2. Sauté the Vegetables: Melt butter in a skillet over medium-high heat. Sauté onions and bell peppers until soft. Add mushrooms and cook for 2–3 more minutes. Stir in cumin.
  3. Make the Sauce: Sprinkle in flour and stir to coat vegetables. Gradually pour in milk, stirring constantly until thickened.
  4. Combine the Ingredients: Mix in mashed squash, corn, green chiles, and the sautéed veggies. Add salt and pepper to taste. Fold in crumbled cornbread and cheese.
  5. Bake: Transfer mixture to a greased baking dish. Bake at 400°F (200°C) for 20 minutes. Optionally, top with extra cheese during the last 5 minutes of baking.

Notes

Great way to use up leftover cornbread. For added heat, use hot green chiles or a pinch of cayenne. You can substitute mushrooms with zucchini or omit them if preferred.
