Why You’ll Love This Recipe

Simple & Quick: Prep is done in just 25 minutes, and the slow cooker does the rest.

Ingredients You’ll Need

Olive oil spray: Used to prevent sticking; feel free to substitute with any cooking oil you have on hand.
1 pound 90% lean ground sirloin beef, or bison: Provides a rich flavor without excessive grease. Ground turkey or sausage can be alternatives.
½ medium onion, diced: Adds a sweet and savory base to the meat.
3 cloves garlic, minced: Garlic elevates the dish with its aromatic flavor.
1 teaspoon kosher salt, divided: Enhances all the flavors; kosher salt is preferred for its texture.
1 teaspoon Italian seasoning: A perfect blend that infuses the sauce with classic Italian flavors.
2 (28-ounce) cans crushed tomatoes: The key sauce ingredient; I recommend using Tuttorosso for consistent quality.
¼ cup water: Helps combine the sauce and captures every bit from the tomato cans.
3 cups part-skim cottage cheese: Creamy and lower in fat than ricotta; for richness, feel free to mix with ricotta.
1 ½ cups part-skim shredded mozzarella cheese, divided: Melts beautifully on top; use fresh mozzarella for an even creamier taste.
¼ cup chopped fresh parsley: Fresh herbs bring a pop of color and brightness.
¼ cup Parmesan cheese, or pecorino romano, freshly grated: Adds a salty, nutty flavor; both are excellent options.
2 large eggs, beaten: Binds the cheese filling together, creating a hearty stuffing.
12 regular uncooked lasagna noodles (11.25 ounces): Avoid no-boil noodles for this recipe; regular noodles cook perfectly in the slow cooker.

How to Make Slow Cooker Lasagna

Sauté the Meat: Spray a large pot over medium-high heat with olive oil. Once hot, add the ground beef and ¾ teaspoon of salt. Sauté for about 3 to 4 minutes until it’s mostly cooked. Then, add the diced onion and minced garlic, cooking for another 2 minutes until they soften and become fragrant.
Create the Sauce: Add the crushed tomatoes and ¼ cup water—swirl it around the can to catch every last drop—and combine with the meat. Season with Italian seasoning and the remaining ¼ teaspoon of salt. Bring the mixture to a boil, then reduce the heat to medium-low and cover. Let it simmer for about 20 minutes, tasting and adjusting salt as needed.
Prepare the Cheese Mixture: While the sauce is cooking, in a large bowl, mix together the cottage cheese (or ricotta), beaten eggs, Parmesan cheese, ½ cup of the mozzarella cheese, and chopped parsley. Set this aside while you layer the lasagna.
Layer in the Slow Cooker: Spray the sides of a 6-quart oval slow cooker with olive oil. Spread 1 cup of the meat sauce on the bottom. Layer 3 lasagna noodles (breaking them to fit if necessary). Add a generous cup of meat sauce followed by ⅓ of the cheese mixture. Repeat this layering process two more times, ending with the last three noodles. Top with any remaining meat sauce.
Cook to Perfection: Cover and cook on low for 3 ½ to 4 hours, or up to 6 hours if necessary. The cooking time can vary, so check for tenderness; poke the center with a knife. If it slides in easily, the noodles are done. If there’s resistance, continue cooking for another 30 to 60 minutes.
Melt the Cheese: Once the noodles are tender, sprinkle the remaining 1 cup of mozzarella over the top. Cover and cook for another 5 to 10 minutes until the cheese is melted and bubbly. Let it sit with the lid off for 10 minutes before cutting into 8 pieces. Garnish with extra parsley if desired.

Storing & Reheating

Leftover Slow Cooker Lasagna can be stored at room temperature for no more than 2 hours. For longer storage, refrigerate in an airtight container for up to 5 days. You can also freeze portions in airtight containers, where it will keep well for up to 3 months. To reheat, simply place in the oven at 350°F until warmed through, about 20-30 minutes, or microwave individual portions until hot. Note that the texture may vary slightly once frozen, but adding a splash of water during reheating can help maintain moisture.

Chef’s Helpful Tips

Keep an eye on the cooking time. Each slow cooker varies, so adjusting time is key based on noodle type and thickness.
If using a thicker cheese like ricotta, consider blending it with cottage cheese to enhance the creaminess and flavor.
Don’t skip the resting time after cooking; it allows the lasagna to set for perfect slices.
If your sauce seems sparse, consider adding a touch of sugar to balance the acidity of the tomatoes.
For a more robust flavor, you can sauté the onion and garlic in a bit of wine before adding the ground beef.
Feel free to mix in vegetables. Spinach or zucchini can blend beautifully and add a nutritious twist!

When it comes to comfort food, few dishes can compete with Slow Cooker Lasagna. It combines layers of deliciousness, easy prep, and satisfying heartiness that’s perfect for family meals. Don’t hesitate to experiment with different cheeses or even add your favorite veggies. Each time you make it, you’ll find new ways to enjoy this classic dish.

Recipe FAQs

Can I use no-boil lasagna noodles?

You can, but it’s best to stick with regular lasagna noodles for this recipe. They hold their texture well while cooking in the slow cooker. No-boil noodles might not absorb moisture and flavors as effectively.

How do I know when the lasagna is done?

Check the tenderness of the noodles by poking the center with a knife. If it slides in without resistance, it’s ready. If you feel any resistance, cook for an additional 30 minutes.

Can I make this vegetarian?

Absolutely! You can replace the ground beef with lentils, mushrooms, or your choice of veggies. Ensure they’re cooked before layering to avoid extra moisture in the sauce.

How can I make this dish gluten-free?

Substitute the regular lasagna noodles with gluten-free lasagna noodles available at most grocery stores. Just keep an eye on the cooking time as they may vary in how long they need to cook.
