Everyone can dig into a cheesy keto casserole. Casseroles are great crowd pleasers and this one will not disappoint! This is one of many family-friendly easy keto recipes to make when you have many mouths to feed.

Cheesy Keto Casserole

Each portion is a real meal – substantial and filling. This is a great recipe for weekly meal prep on a keto diet.

I’ve struggled with other approaches to gluten-free, low-carb casseroles. Typically, they end up too light and fluffy (thanks to all the egg and cream cheese combos) to be considered a complete meal on their own. The combination of mushrooms, greens, eggs and cheese in this cheesy keto casserole is kept in perfect balance.

Make cheesy keto casserole stuffed with spinach and mushrooms for breakfast; Save leftovers for a quick lunch or dinner.

My favorite aspect of a ketogenic diet is being able to feel good on simple recipes without all the bloating, gas, and energy dips that come along with carb-rich foods.

Take the cheesy keto casserole to go in a packed lunch with a can of wild-caught fish and an avocado on the side. It’s easy, it’s quick, and will keep you fueled through a long work day. This is the kind of food that works with you, not against you!

The flavors listed in the recipe below provide a reliable base for you to mix and match other things you have on hand. Keep the proportions relatively the same but feel free to get creative and use up whatever little bits of ingredients you already have on hand. Casseroles, like ketogenic omelets, are excellent recipes to fill with leftovers. Check your fridge, do you have any spare sprigs of fresh herbs, a handful of lonely greens, or leftover veggies?

Substitute Swiss chard with any green like arugula, kale, other low oxalate choice. Add your favorite seasoning to the eggs before baking. Do you like Italian, Mexican or Curry blends? Toss in a teaspoon or two of your favorite mix!

This recipe is easily doubled to fill a 9 x 13-inch baking dish.
