Casserole night just got a keto makeover. These 30 low-carb bakes swap the pasta, rice, and breadcrumbs for cauliflower, zucchini, and plenty of melted cheese, so you get all the comfort without the carb crash.
Inside you’ll find cheesy chicken dinners, hearty ground beef bakes, a couple of breakfast options, and veggie sides that vanish fast.
Most come together in one pan and reheat beautifully for meal prep. Let’s build a whole week of cozy dinners that keep you full and on track.
1. Keto Chicken Bacon Ranch Casserole
All the flavor of the dip in a forkable dinner. Cooked chicken and broccoli get folded into a homemade ranch cream sauce, then topped with cheddar, mozzarella, parmesan, and crispy bacon before baking at 350°F for about 20 minutes.
There are no noodles here, so broccoli does the heavy lifting and keeps it at 4 grams net carbs per serving. It bakes up browned and bubbling, and a heaping tablespoon of ranch seasoning saves you from measuring out five separate dried herbs.

2. Keto Cheeseburger Casserole
This one tastes like a bacon cheeseburger with none of the bun. Ground beef gets bound with cream cheese, diced dill pickles, and keto ketchup, then buried under melted cheddar. Bake it at 350°F for 30 minutes, or pressure cook it in a single minute.
A quick mayo, mustard, and pickle-juice sauce plus shredded romaine and tomato on top sells the burger illusion. It lands at just 3 grams net carbs and keeps in the fridge for two days.

3. Keto Sausage Breakfast Casserole
Think of this as a giant cheesy omelette baked in a dish. Twelve eggs, a pound of browned breakfast sausage, cheddar, heavy cream, and broccoli go in with no bread or potatoes to weigh it down. It bakes at 375°F for about 30 minutes until fluffy and set.
At 3.2 grams net carbs per slice, it is genuinely filling. Assemble it the night before and refrigerate it unbaked, or freeze it, so busy mornings only need the oven.

4. Cheesy Taco Casserole
Taco Tuesday goes low-carb without anyone complaining. Seasoned ground beef, Ro-Tel tomatoes with green chiles, and cauliflower rice get layered under a blanket of Mexican-blend cheese, then baked about 30 minutes until the top is lightly browned.
The cauliflower rice stands in for regular rice and keeps it at 5 grams net carbs. The trick is draining the Ro-Tel well and cooking the cauliflower long enough to dry it out, so the casserole holds together instead of going watery.

5. Keto Chicken Broccoli Casserole
Weeknight comfort that comes together in about 25 minutes. Fresh broccoli and tender cooked chicken get coated in a cheesy mozzarella and parmesan sauce, then topped with more melted cheese and baked until bubbly.
There are no noodles or rice, so it stays under 5 grams net carbs per serving. The recipe leans on chicken thighs rather than breasts for richer flavor, though either works fine.
It is the kind of cozy, cheesy bake that even non-keto eaters happily go back for.

The casserole that proves tuna noodle doesn’t need noodles. Shredded cabbage stands in for the pasta, simmered with albacore tuna, mushrooms, green beans, and a thyme-spiked cheddar cream sauce.
It starts in one skillet, where the sauce reduces for 15 minutes, then bakes at 425°F until the cheese bubbles. A scatter of crushed pork rinds on top brings back that classic crunchy topping. Each of the eight servings comes in at 4 grams net carbs.
