Crockpot Lasagna gives you all the comfort of a classic layered lasagna with a much simpler hands-off cooking method. Uncooked noodles, savory beef marinara, creamy ricotta, and mozzarella cook together until tender, cheesy, and ready for a satisfying family dinner.
Lasagna is always welcome at the dinner table, but traditional versions can require plenty of boiling, assembling, and oven watching. Using your slow cooker keeps the process more manageable while still giving you those familiar layers of pasta, rich tomato sauce, beef, and melted cheese.
The uncooked noodles are especially convenient because they soften right inside the crockpot. A little added water provides the moisture they need, while the meat sauce and cheeses surround the pasta as everything slowly cooks together. Choose the HIGH setting when dinner needs to be ready sooner or let it cook gently on LOW for an easy meal later in the day.
Crockpot Lasagna Ingredients
Ground beef: Extra-lean ground beef creates the hearty base of the meat sauce without adding too much excess grease.
Yellow onion: Chopped onion cooks with the beef and brings mild sweetness and savory depth to the sauce.
Garlic: Freshly minced garlic gives the beef mixture a classic aromatic flavor.
Tomato sauce: The marinara-style sauce provides plenty of moisture for the pasta while creating the rich tomato layer throughout the lasagna.
Salt and black pepper: Simple seasoning enhances both the beef and tomato sauce.
Water: A small amount poured around the sides helps the dry lasagna noodles become tender while they slow-cook.
Lasagna noodles: Standard dry noodles go directly into the crockpot without boiling first. Break them as necessary to fit the shape of your slow cooker.
Ricotta cheese: Ricotta adds the soft, creamy layer that contrasts with the meat sauce and pasta.
Mozzarella cheese: Shredded mozzarella melts between the layers and over the top for the familiar cheesy lasagna finish.
Fresh basil or parsley: Either herb adds a fresh finishing touch just before serving.
Nonstick cooking spray: Coating the crockpot makes serving easier and helps keep the edges from sticking.
Step-by-Step Crockpot Lasagna
STEP 1: Place the ground beef in a large skillet over medium-high heat. Cook it while breaking it into small crumbles. When the meat is nearly cooked through, stir in the chopped onion and garlic. Season with salt and freshly ground black pepper, then continue cooking until the beef is done and the onion has begun to soften.
STEP 2: Add one jar of tomato sauce to the cooked beef mixture. Stir everything thoroughly so the beef is evenly coated, then let the sauce cook for another couple of minutes. Remove the skillet from the heat while you prepare the crockpot.
STEP 3: Coat the inside of the slow cooker thoroughly with nonstick cooking spray. Spoon just enough of the beef sauce into the bottom to create a thin layer. This gives the first pasta layer moisture underneath and keeps the noodles from resting directly against the crockpot.
STEP 4: Arrange dry lasagna noodles over the sauce. Since crockpots are usually round or oval instead of rectangular, snap the noodles into smaller pieces as needed. Add spoonfuls of ricotta over the noodles, sprinkle with mozzarella, and cover with another portion of beef sauce.
STEP 5: Repeat the layering process with more noodles, ricotta, mozzarella, and meat sauce. Continue until the ingredients have been used, aiming for about three substantial layers. The exact number may vary depending on the size and shape of your slow cooker.
STEP 6: Pour the remaining tomato sauce evenly over the final layer and scatter the remaining mozzarella across the top. Slowly pour the water around the outside edges rather than directly over the center. Cover the crockpot securely.
STEP 7: Cook on HIGH for about 3 hours or LOW for about 6 hours. The lasagna is ready when the noodles are completely tender and the cheese is melted and bubbling. Let it stand for several minutes before cutting into portions, then finish with chopped basil or parsley.
How to Store & Reheat
Allow leftover lasagna to cool before transferring it to an airtight container. Refrigerate it promptly and plan to enjoy it within about 3 to 4 days.
Individual portions are particularly convenient for reheating. Warm them in the microwave until thoroughly heated, or place several portions in a covered baking dish and reheat in the oven. Covering the lasagna helps prevent the pasta and cheese from drying out as they warm.
You can also freeze cooked portions for longer storage. Wrap the cooled pieces well or place them in freezer-safe containers and freeze for up to 2 to 3 months. Thaw frozen lasagna in the refrigerator overnight before reheating for the most even results.
Do you have to cook lasagna noodles first?
No. One of the biggest conveniences of this slow cooker method is that the lasagna noodles go into the crockpot completely dry. The tomato sauce and added water provide enough moisture to soften them gradually as the dish cooks.
Make sure the pasta is surrounded by sauce rather than leaving large dry areas exposed. Proper moisture distribution is the key to getting tender noodles without boiling them separately.
Can I cook crockpot lasagna on LOW instead of HIGH?
Yes. Cook the lasagna for approximately 6 hours on LOW instead of about 3 hours on HIGH. The slower setting is useful when you want to assemble the meal earlier in the day and have it ready around dinnertime.
Cooking times can vary slightly between slow cookers, so use noodle tenderness as the most important indication that the dish is finished.
Why do you add water around the lasagna?
The water provides additional moisture for the uncooked noodles. As the crockpot heats, the pasta absorbs liquid from both the tomato sauce and the added water, allowing it to soften without being boiled first.
Pouring the water around the edges helps distribute that extra moisture without washing the cheese away from the top layer.
How do I keep crockpot lasagna from getting watery?
Use extra-lean beef and drain off excess grease if necessary before adding the tomato sauce. It is also important to use only the specified amount of additional water.
Once cooking is complete, let the lasagna rest for several minutes before serving. This short resting period allows the layers to settle and makes the portions easier to lift from the slow cooker.
Can crockpot lasagna be made ahead?
You can prepare the beef sauce ahead of time and refrigerate it until you are ready to assemble the lasagna. This can make morning preparation especially quick.
For the best noodle texture, assemble the complete lasagna relatively close to the time you plan to begin cooking rather than leaving dry noodles sitting in the sauce for an extended period before turning on the slow cooker.
Serving Ideas for Crockpot Lasagna
A simple green salad is a fresh, crisp side that balances the rich beef, ricotta, and mozzarella layers without making dinner feel too heavy.
Garlic bread is another natural pairing, especially when you want something for scooping up the extra tomato sauce left on the plate.
For a vegetable side, try roasted or steamed green vegetables such as broccoli or green beans. Their straightforward flavor complements the cheesy pasta while keeping the meal easy to put together.
Helpful Tips
- Cover the noodles with sauce. Dry pasta needs contact with enough moisture to cook properly, so avoid leaving large sections of noodles uncovered between layers.
- Break the noodles to fit. There is no need for perfectly shaped pasta layers. Snap the dry noodles into whatever pieces are necessary to cover most of the crockpot.
- Give it time to rest. Letting the finished lasagna sit for several minutes helps the cheese, sauce, and pasta settle, giving you cleaner portions when it is time to serve.
Crockpot Lasagna
Ingredients
Meat Sauce
- 2 garlic cloves finely minced
- 2 jars tomato sauce 22 fl oz each, such as Classico Sweet Basil Marinara
- 1/2 teaspoon freshly ground black pepper
- 1 yellow onion chopped
- 1 pound extra-lean ground beef
- 1/2 cup water
- 1/2 teaspoon salt
- Nonstick cooking spray as needed
Lasagna Layers
- 2 cups mozzarella cheese shredded
- 1 pound dry uncooked lasagna noodles
- 1 container ricotta cheese 16.8 ounces
Garnish
- Chopped fresh basil or parsley as desired
Instructions
- Place the ground beef in a large frying pan over medium-high heat. Cook while breaking the meat into smaller pieces with a spoon.
- When the beef is almost completely cooked, add the chopped onion and minced garlic. Season the mixture with the salt and black pepper, then stir thoroughly.
- Pour one 22-fluid-ounce jar of tomato sauce into the skillet. Stir until evenly combined and allow the mixture to cook for another couple of minutes so the flavors come together. Remove the pan from the heat.
- Coat the interior of the crockpot generously with nonstick cooking spray.
- Spread a small portion of the prepared meat sauce across the bottom, forming a thin and even base.
- Arrange a layer of uncooked lasagna noodles over the sauce, snapping the noodles into smaller pieces wherever necessary so they fit inside the slow cooker.
- Distribute spoonfuls of ricotta over the pasta, followed by a portion of the shredded mozzarella. Cover the cheeses with another layer of the meat sauce.
- Continue layering in the same order—lasagna noodles, ricotta, mozzarella, and meat sauce—until the ingredients have been used or the crockpot is filled. This generally produces approximately three layers.
- Pour the second 22-fluid-ounce jar of tomato sauce evenly across the uppermost layer.
- Scatter any remaining mozzarella over the surface.
- Carefully pour the 1/2 cup of water around the outer edges of the lasagna. This additional moisture helps the uncooked noodles soften evenly while preventing the dish from becoming dry.
- Cover the crockpot securely. Cook on HIGH for 3 hours or on LOW for 6 hours, continuing until the lasagna noodles are tender and the cheese is thoroughly melted and bubbling.
- Allow the finished lasagna to stand for several minutes after cooking.
- Finish with a generous sprinkling of freshly chopped parsley or basil before serving.
