Low-Carb Yellow Squash Casserole

Step 1
Preheat the oven to 400 degrees F (200 degrees C).

Step 2
Heat olive oil and butter in a skillet over medium-high heat; cook and stir onion and garlic in the hot oil-butter mixture until softened, about 3 minutes. Add squash, salt, and pepper; stir to combine. Cover skillet and cook, stirring occasionally, until squash is softened, about 5 minutes. Transfer squash mixture to a large bowl.

Step 3
Mix raw almonds and 1/2 cup shredded cheese together in a bowl; stir into squash mixture. Whisk cream and eggs together in a measuring cup or small bowl; stir into squash mixture. Pour squash mixture into a 9×13-inch casserole dish; top with remaining shredded cheese and roasted almonds.

Step 4
Bake in the preheated oven until casserole is golden brown and bubbling, 25 to 30 minutes.
