Elevate your weeknight dinners with Crockpot Lasagna! Ideal for on-the-go families, this dish requires just a handful of ingredients and minimal prep. Come home to a warm, delicious meal that’s ready to serve.
Recipe Science
- Layering uncooked lasagna noodles in the crockpot allows them to absorb moisture from the sauce, cooking them evenly and eliminating the need for pre-boiling.
- Slow cooking the lasagna ensures that the flavors meld together over time, resulting in a rich, cohesive dish with tender noodles and well-incorporated sauce and cheese.
- The consistent low heat of the crockpot prevents the lasagna from burning or drying out, maintaining a moist texture throughout the cooking process.

Why It Works
I’ve made my classic homemade lasagna into an easy crockpot lasagna recipe. The good news is you don’t have to pre-cook the pasta. It’s a perfect meal to assemble, then let the slow cooker do the work!
The vegetables and meat are browned and seasoned, then combined with marinara sauce. The trickiest part is how to layer the dried lasagna noodles into the pot. Don’t worry! I’ll show you step-by-step my layer techniques for crockpot casserole success.
Ingredients You’ll Need
- Pasta: Use regular lasagna noodles, 9 pieces, about 7 ½ ounces. No-boil (over-ready) lasagna can be used but will cook faster and have a softer texture.
- Meat: Use 85 to 90% lean ground beef and fresh Italian pork sausage. Use mild or spicy sausage, depending on your heat tolerance.
- Tomato Sauce: Use my marinara sauce recipe or, for convenience, store-bought sauce. You’ll need 56 ounces.
- Seasonings: To season the meat sauce, saute chopped onion and minced garlic. Add dried Italian seasoning for a concentrated flavor, salt, and pepper.
- Cheese: For a creamy filling, combine ricotta cheese, parmesan cheese, and chopped parsley. Add grated mozzarella cheese between each layer.
See the recipe card below for all ingredients and measurements (US and metric).
Ingredient Substitutions
Once you’ve learned how to make lasagna in a crockpot, here are some delicious ways to switch up the flavor. Try them in your next batch!
- Tomatoes: Make a quick tomato sauce with a few tablespoons of tomato paste and crushed tomatoes. Saute fresh diced tomatoes to add to the sauce.
- Meat: Make it hotter with spicy Italian sausage. Use ground turkey or chicken instead of ground beef.
- Spicy: Add red chili flakes to the marinara sauce, minced hot peppers, or hot sauce.
- Vegetables: Saute sliced mushrooms, bell peppers, eggplant, or zucchini. Do not add the vegetables raw to the lasagna.
- Cheese: Instead of ricotta, use cottage cheese, crème fraîche, or cream cheese. Use Pecorino Romano or Parmigiano Reggiano.
How to Make Crockpot Lasagna
Step 1: Saute the Aromatics
In a large pan or pot, saute the onions and garlic in olive oil. This brings out the onions’ natural sweetness and mellows out the pungent alliums.
Step 2: Brown the Meat
The meat should be browned on the stovetop before adding it to the slow cooker. Add the beef and sausage to the pan.
Sauteing the ground beef and sausage adds more flavor to the surface. Season the meat with dried Italian seasoning, salt, and pepper.
Step 3: Add the Marinara Sauce
Add the marinara sauce and water, then simmer for 10 minutes. This makes the sauce hot, and it will cook the dried pasta faster. You can make the sauce a few days before assembling and then reheat it.
Mix all the ingredients together with a spoon or spatula until combined.
Pro Tip: Three types of cheese add a rich and creamy layer to the crock pot lasagna. I use a combination of whole milk ricotta cheese, grated parmesan cheese, and shreds of melty mozzarella to bind the layers together.
Step 5: Layer the Ingredients
A) Add 1 cup of meat sauce to cover the bottom of the dish.
B) Layer 3 sheets of the dried lasagna, breaking up the pieces to cover any gaps.
C) Add ⅓ of the ricotta cheese mixture.
D) Add ⅓ of the mozzarella cheese.
Pro Tip: Use a 6-quart Crockpot for cooking a large batch, about 8 to 10 servings. Lightly grease the bottom and sides of the pot with olive oil or cooking spray to prevent sticking.
Cook’s Notes: After the initial first layer, repeat the process two more times. I typically add ⅓ meat sauce between layers, then pour in and spread 1 cup of meat sauce on the top layer.
For the dried lasagna, I like to keep one piece whole (breaking a small portion from the bottom to fit into the pot), then break one in half, and then one into quarters. For the final addition, pour ½ cup of water along the sides of the pot to hydrate the pasta and create a hot and steamy cooking environment.
Step 6: Cook the Lasagna
Cover the slow cooker lasagna and cook for 3 ½ to 4 hours. This duration gives plenty of time for the uncooked noodles to absorb water from the surrounding ingredients, like the tomato sauce and ricotta cheese. The cooked pasta should be tender when ready.
To be completely cooked, the internal temperature should reach between 160 to 175ºF (71 to 79ºC).
Step 7: Melt Extra Cheese on Top
Add the remaining 1 cup of grated mozzarella cheese on top, then cook until melted, about 15 minutes on low setting.
Step 8: Ready to Serve
Serve right away, or keep on warm. The slices will hold together better when not so hot.
Frequently Asked Questions
The lasagna can be assembled in the crockpot insert, covered, and refrigerated. However, cooking times will be longer because all ingredients will be cold. Make sure to add 1 to 1 ½ hours of extra time.
No! Since the cooking time is about four times longer than baking the casserole, this gives plenty of time for the noodles to cook by absorption. The recipe has been designed to add extra water to the pot to hydrate the pasta since it’s not boiled in water.
Follow the ratios of the ingredients in the recipe. If you still find that the noodles turn out too wet, omit the 1 cup of water added to the sauce. Reduce cooking time by 30 minutes so the texture is not as soft.
High setting will take about 2 to 2 ½ hours. However, there is a risk of cooking it unevenly. The edges will cook and brown faster, but the center needs time to hydrate and soften.
Pasta producers have developed no-boil (oven-ready) dried lasagna sheets to reduce prep time. These are thinner than regular dried lasagna and have been pre-cooked and dehydrated. This means that if used to make slow cooker lasagna, the texture will be softer, not as sturdy, and cook much quicker. I recommend cooking for 1 ½ to 2 hours. Add more time as needed to tenderize the noodles.

Instructions
- Saute the Aromatics – In a large pot or Dutch oven, heat olive oil over medium-low heat. Sauté the onions until translucent, about 2 minutes. Add garlic, and cook for 30 seconds.
- Brown the Meat – Add the beef and sausage to the pan. Turn the heat to medium-high, break into smaller pieces. Cook until no pink remains, about 3 to 5 minutes. Stir in the salt, Italian seasoning, and black pepper.

- Make the Cheese Mixture – In a medium bowl, combine ricotta cheese, parmesan cheese, and chopped parsley. Set aside.
- Layer the Lasagna – Reserve 2 cups of meat sauce and 1 cup of grated mozzarella cheese. Lightly grease the bottom and sides of a 6-quart slow cooker with olive oil or cooking spray. Add 1 cup of meat sauce to cover the bottom of the dish to prevent sticking. Layer 3 sheets of the dried lasagna noodles, breaking up the pieces to cover any gaps. Evenly add ⅓ of the ricotta cheese mixture, ⅓ of the mozzarella cheese, and ⅓ meat sauce. Repeat for 2 more layers. On the top layer, pour on the 1 cup of reserved meat sauce. Pour ½ cup of water along the sides of the pot.
- Slow Cook the Lasagna – Cover and cook for 3 ½ to 4 hours on the Low setting. The noodles should be tender, with most of the liquid absorbed.

Notes
- Make-Ahead: The meat sauce and cheese filling can be made and refrigerated 2 days in advance. Reheat the sauce before assembling. Alternatively, the lasagna can be assembled 2 days in advance. Add 1 to 1 ½ hours of cooking to account for the cold insert and ingredients.
- Storing: Refrigerate for up to 5 days. Freeze for up to 3 months, defrost before reheating.
- Reheating: Reheat slices in the microwave until warmed through, about 1 to 1 ½ minutes.
- If using my homemade marinara sauce, double the sauce recipe.

Hi I saw this recipe and thought I have everything to make it.
My husband and I will make this more offeren then regular lasagna because it’s easy and very yummy 😋
I did make the mistake of using no-boil noodles and the noodles were over done so I won’t do that again.
Thank you for your great recipes. Have a wonderful Thanksgiving Teresa.

Thanks for your feedback!
Dave says
I don’t see the quantity of noodles listed. I assume it would be 9 sheets since there are 3 layers.
Jessica Gavin says
Thanks for letting me know, Dave! The recipe has been updated. Use about 9 lasagna sheets, or as needed to cover each layer.
Mitch B says
This reads as if you are adding 56 fl. oz. of sauce. Are you really adding 7 cups of sauce or is the 56 oz. the weight of the tomatoes used in your marinara sauce recipe?? Your marinara recipe yields 3 cups of finished sauce which sounds more logical, especially if I were using a purchased jarred sauce instead of yours.
Jessica Gavin says
Thanks for the catch! Use 46 ounces, or two 23 ounce jars of marinara sauce if you are purchasing at the store.
