Zucchini & Yellow Squash Casserole

Paula Todora


Cheesy and Baked until golden brown, this is one of favorite side dishes. Low-Carb/Keto-Friendly with less than 3 net grams carbs per servind/8 servings per recipe. It makes a 9x13-inch baking dish, and leftovers are great. I've also frozen it before cooking and after cooking-it does well on both accounts.

How to Make Zucchini & Yellow Squash Casserole


  1. Preheat oven to 400 degrees F.
  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. Cook, stirring occasionally, until squash is softened, about 5-10 minutes. Transfer squash mixture to a large bowl.
