31 Delicious Keto Casserole Recipes to Satisfy Your Low-Carb Cravings

When you’re craving comfort, sometimes only a casserole will do. I love trying out new casserole recipes and we’ve recently been eating more low-carb meals. I’ve been experimenting with ingredients and I’ve got some really tasty keto-friendly casserole recipes to share.

Don’t get me wrong, we don’t follow the keto diet religiously but we do try to fit in at least one low carb meal each week. Most of these recipes contain really simple ingredients that you’ll probably already have in, but nothing is too fancy or expensive so they’re great for those watching their budgets.

As well as sharing some of my own recipes, I’ve also gathered some really tasty keto casserole recipes from other food bloggers too.

Equipment You’ll Need

• Oven-Safe Casserole Dishes: It’s a good idea to have a mix of 9×9 and 9×13 baking dishes so you can make casseroles to suit the number of people you’re serving. I tend to use a larger casserole dish as there are five of us most nights.

• Large Mixing Bowls: These come in super handy for combining creamy sauces, eggs, cheese, and vegetables before baking.

• Skillet or Sauté Pan: Used for browning meats, sautéing vegetables, and building flavor before everything goes into the oven.

• Cutting Board: A decent cutting board is essential for prepping vegetables, meats, and fresh herbs.

• Sharp Chef’s Knife: Makes slicing zucchini, cauliflower, mushrooms, and other keto-friendly veggies quick and easy.

• Measuring Cups and Spoons: Keeps ingredients and seasonings balanced, especially for sauces and spices.
