This keto air fryer lasagna bake layers seasoned beef, Italian sausage, low-carb marinara, ricotta, mozzarella, and Parmesan without noodles. After preparing the meat sauce, air fry at 320°F (160°C), checking after 8 to 10 minutes. Continue until the center reaches 165°F (74°C).

Skipping the noodles makes this lasagna easier to assemble and keeps the focus on the meat sauce and cheese. Choose an oven-safe dish with enough capacity for the ingredients that also fits your air fryer with room for airflow. Divide the mixture between suitable dishes if necessary.

The recipe makes six modest servings. Pair one with a vegetable or salad for a complete meal, or divide it into larger portions if it is the entire dinner.

Why this noodle-free air fryer lasagna works

The beef and sausage are fully browned on the stovetop before the casserole enters the air fryer. That means the short air-frying time only needs to heat the sauce, soften the ricotta layer, and brown the mozzarella.

Pressing the meat sauce into an even layer and distributing spoonfuls of the ricotta mixture across the pan prevents one heavy pocket of cheese. A low-carb marinara keeps the carbohydrate count lower, but check the label because added sugar varies considerably by brand.

Ingredients

Quick heads-up: This post contains Amazon affiliate links. As an Amazon Associate I earn from qualifying purchases.

Ground beef and Italian sausage: The combination gives the sauce a hearty texture and traditional lasagna flavor. Drain the excess grease after browning.

White onion: Cook it with the browned meat until it begins to soften.

Low-carb marinara: Use one cup and check its serving size and added-sugar information. Rao's is the brand used in the original recipe.

Salt, pepper, and Italian seasoning: These season the meat sauce and cheese mixture. The Italian seasoning is divided between them.

Ricotta, mozzarella, and Parmesan: Ricotta forms the creamy middle layer, while mozzarella melts across the top and Parmesan adds a salty finish.

Parsley: Optional, but useful for a fresh finish.

What pan fits in the air fryer?

Use an oven-safe baking dish that fits inside your basket with room around it for airflow and sufficient clearance above the food. Check its capacity before filling it; do not assume a six-inch pan can hold three quarts. Divide the mixture between suitable dishes if needed rather than overfilling.

How to make keto lasagna in an air fryer

Brown the beef and pork sausage together until fully cooked to 160°F (71°C), then drain the grease. Color alone is not a reliable doneness test. Add the onion and cook for 2 to 3 minutes. Stir in the marinara, salt, pepper, and 1 teaspoon of Italian seasoning and let the sauce simmer for 5 minutes.

While the sauce simmers, mix the ricotta with 1/4 cup mozzarella, 4 tablespoons Parmesan, the remaining Italian seasoning, and a pinch of salt.

Press the meat sauce into an even layer in the pan. Add spoonfuls of the ricotta mixture and gently spread them into a level layer. Finish with the remaining mozzarella.

Air fry at 320°F (160°C), checking after 8 to 10 minutes. Continue until the center reaches 165°F (74°C), even if the cheese is already melted. Pan depth and a refrigerated starting temperature can extend the cooking time. FoodSafety.gov recommends 165°F (74°C) for casseroles. Let the lasagna rest for 5 minutes before serving so the layers settle.

Nutrition and portion information

The original calculation divides the recipe into six servings. Each serving has approximately 386 calories, 3.6 grams of total carbohydrates, 0.3 grams of fiber, 3.3 grams of net carbohydrates, and 14.3 grams of protein. Treat those numbers as estimates because sausage, marinara, and cheese brands can change them substantially.

Troubleshooting

The center is not hot: Pan depth and air fryer power affect the timing. Continue cooking in 2-minute increments until a thermometer in the center reads 165°F (74°C). Bubbling sauce alone does not confirm that the center is ready.

The cheese browns before the center heats: Cover the pan loosely with air-fryer-safe foil, secure it so it cannot lift, and continue cooking. Remove it for the final minute if the top needs more color.

The lasagna is watery: Drain the meat thoroughly and use a thick marinara. Letting the finished bake rest also helps the layers hold together.

The pan does not fit: Divide the mixture between smaller air-fryer-safe dishes instead of forcing a pan against the basket walls.

Storage and reheating

Refrigerate leftovers promptly in a covered container for up to 3 days. Reheat a portion in an air-fryer-safe dish at 300°F (150°C), checking after 4 to 6 minutes. Continue until the center reaches 165°F (74°C); thickness and starting temperature affect the time needed.

Frequently asked questions

Does keto lasagna need noodles?

No. This recipe leaves them out entirely and layers seasoned meat sauce with ricotta, mozzarella, and Parmesan.

Do I need to preheat the air fryer?

The original method calls for preheating to 320°F (160°C). If your model does not have a preheat cycle, run it at the cooking temperature for about 3 minutes before adding the pan.

Can I make the lasagna ahead?

You can prepare the meat sauce and ricotta mixture ahead and refrigerate them separately. Assemble the pan shortly before cooking. A fully chilled assembled lasagna may need additional air-frying time.
