Embrace the heartwarming flavors of fall with our Delicious Squash Casserole recipe, a cheesy blend of seasonal squash, aromatic herbs, and dreamy cheeses that's a surefire hit at any dinner table.
Preheat your oven to 350°F. Grease a casserole dish with spray and set it aside.
In a large skillet, melt the butter over MEDIUM heat. Add the diced onion and minced garlic, sautéing for 2-3 minutes, until the onions become translucent and fragrant.
Add the sliced squash to the skillet. Cook for about 5 minutes, until they soften slightly. Stir in the thyme, oregano, salt, and black pepper.
In a separate mixing bowl, whisk the sour cream and eggs until well combined. Stir in all one cup of cheddar. Add in the squash and onion mix, and stir to coat completely.
