How to Make southern squash casserole
Prepare Your Ingredients: Begin by washing your yellow squash and zucchini thoroughly. Slice them into thin rounds, aiming for uniform sizes for even cooking. Dice your onion finely so it blends seamlessly with the other ingredients.
Sauté Vegetables: Heat a bit of olive oil in a skillet over medium heat. Add the sliced squash, zucchini, and onions until they soften slightly—about 5-7 minutes. The aroma will fill your kitchen like an inviting hug.
Combine Ingredients in a Bowl: In a large mixing bowl, combine sautéed veggies with shredded cheddar cheese, sour cream, eggs, salt, and pepper. Mix gently until everything is well incorporated; this will create a creamy filling that binds beautifully.
Add Breadcrumbs Topping : Transfer the mixture to a greased baking dish. Top generously with breadcrumbs, ensuring even coverage for that perfect crunch when baked—this will add delightful texture to each bite!
Bake Until Golden Brown : Preheat your oven to 350°F (175°C). Bake uncovered for about 30-35 minutes or until bubbly and golden brown on top. The smell will make you feel like you’re home again!
