High-protein slow cooker lasagna made with regular lasagna noodles that cook right in a hearty meat sauce. Easy, family-friendly, and perfect for weekends with great leftovers.
12regular uncooked lasagna noodles(such as Barilla 11.25 ounces (not no-boil))
Instructions
Spray a large pot over medium-high heat with oil, when hot add the ground beef and ¾ teaspoon salt. Sauté for about 3 to 4 minutes, or until the ground beef is mostly cooked then add the onion and garlic and cook until soft, 2 minutes.
Add the crushed tomatoes and ¼ cup water (swoosh it around the tomato can to get every last bit) then add to the pot.
Season with Italian seasoning, remaining ¼ teaspoon salt and bring to a boil, reduce the heat to medium-low, cover and simmer for about 20 minutes. Taste for salt and adjust as needed.
Meanwhile while the sauce cooks, in a large bowl, mix together the cottage cheese (or ricotta), beaten eggs, Parmesan cheese, ½ cup of the mozzarella, and the chopped parsley. Set aside.
Spray the sides of an oval 6-quart slow cooker with olive oil, then spread 1 cup of meat sauce on the bottom. Layer 3 lasagna noodles (break them to fit if needed), add 1 generous cup meat sauce, followed by ⅓ of the cheese mixture. Repeat this process 2 more time, finishing with the last 3 noodles. Top with the remaining sauce (you might have a little extra).
Cook on low for 3 ½ to 4 hours, or as long as 6 if needed (time will vary depending on your slow cooker and the noodles you use). At the 3 hour mark, poke the center with a knife to see if the noodles are tender, if it slides in easily and noodles feel tender it’s done. If there’s resistance, add another 30 to 60 minutes.
When noodles are tender, sprinkle the remaining 1 cup mozzarella over the top, cover, and cook until the cheese is melted, 5 to 10 minutes. Let it stand for 10 minutes with the lid off, then cut into 8 pieces. Garnish with parsley, if desired.
Notes
Add in some veggies like spinach, or add mushrooms to the sauce.
Store the leftovers in the fridge for 4 days in airtight containers.
Freeze for up to 3 months in freezer-safe containers. Thaw in the fridge then reheat or cook as normal.
Tips for Perfect Lasagna in the Slow Cooker
Use regular, uncooked lasagna noodles. They soften during cooking and hold their shape better than no-boil noodles in the slow cooker.
Start with sauce on the bottom. This prevents sticking and ensures the noodles hydrate evenly instead of drying out.
Don’t skimp on sauce. Slow cookers don’t reduce liquid like the oven does, but the noodles still need enough moisture to cook through, so I used more sauce than my baked recipe.
Keep the lid closed. Each time you lift it, you lose heat and moisture, which can result in undercooked or gummy noodles.
Cook on low, not high. I know you might be tempted, but trust the process. Low heat gives the noodles time to soften evenly and prevents the cheese layer from separating.
Let it rest before slicing. Resting for at least 15 minutes helps the layers set, so it slices cleanly instead of turning into lasagna soup.
Add the mozzarella at the end. Sprinkling it on during the final 5 to 10 minutes keeps it melty and gooey instead of overcooked.
