Ingredient Checklist

• nonstick cooking spray
• 1 lb extra-lean ground beef
• 1 yellow onion, chopped
• 2 cloves garlic, minced
• 1/2 tsp salt
• 1/2 tsp black pepper
• 2 jars (22 fl oz each) tomato sauce (like Classico sweet basil marinara)
• 1/2 cup water
• 1 lb uncooked lasagna noodles
• 1 tub (16.8 oz) ricotta cheese
• 2 cups shredded mozzarella cheese
• fresh parsley or basil, chopped

Assemble and Cook in the Crockpot

1. Heat a large frying pan over medium-high and brown 1 lb extra-lean ground beef, breaking it up as it cooks.
2. When the beef is almost cooked, add 1 chopped yellow onion and 2 minced garlic cloves; season with 1/2 tsp salt and 1/2 tsp black pepper, stir, pour in one jar (22 fl oz) tomato sauce, simmer about 2 minutes, then remove from heat.
3. Drain any excess fat from the meat mixture if necessary.
4. Spray the inside of a 5–7 quart slow cooker with nonstick cooking spray and spoon a thin layer of meat sauce onto the bottom.
5. Layer uncooked lasagna noodles over the sauce, breaking noodles as needed to fit.
6. Add spoonfuls of ricotta cheese and sprinkle shredded mozzarella over the noodles, then spoon more meat sauce on top; repeat layers until the slow cooker is full (about 3 layers).

7. Pour the second jar (22 fl oz) of tomato sauce evenly over the top and scatter the remaining mozzarella cheese.

   

8. Slowly pour 1/2 cup water around the edges of the lasagna to help the noodles steam and cook.
9. Cover the crockpot and cook on high for 3 hours or low for 6 hours, do not lift the lid while cooking, until noodles are tender and the cheese is bubbling.
10. Let the lasagna rest for at least 15 minutes before slicing.
11. Sprinkle with chopped fresh parsley or basil before serving.

Kitchen Tips and Shortcuts

Make sure to brown your ground beef before adding it to the slow cooker and drain any extra fat. Skipping this step could leave you with a greasy, bland sauce. You can see this quick browning-and-draining step in Slow Cooker Hamburger Hash.

Keep your noodle layers thin and even, breaking noodles as needed so you don’t get crunchy or undercooked spots.

Don’t forget the 1/2 cup of water—the steam it creates is what cooks the noodles fully and keeps the edges from drying out.

Once you cover the crockpot, resist the urge to peek. Every time you lift the lid, add 15-20 minutes to your cooking time. That rule holds for low-and-slow cuts like Slow Cooker Beef Brisket, too.

Let the lasagna rest for at least 15 minutes before cutting into it. This help it hold its shape nicely on the plate.

Swap Ideas and Add-Ins

Feel free to adapt this crockpot lasagna recipe with what you have on hand:

• Ground meat: Try ground turkey, chicken, or Italian sausage for a different twist. If you use sausage, skip or cut back on added salt since sausage is already seasoned. Have extra ground beef or turkey? Try this Slow Cooker Taco Casserole for another easy weeknight option.
• Ricotta cheese: Cottage cheese works well—drain it and blend for a smoother texture if you like. Or mix cream cheese with sour cream for a creamy kick.
• Lasagna noodles: Regular dried noodles work best, but if you only have no-boil noodles, add an extra 1/4 cup water to help them cook fully in the crockpot.
• Mozzarella cheese: Swap for provolone, a blend of Italian cheeses, or sprinkle some Parmesan for extra flavor. Just keep about 2 cups total cheese.
• Tomato sauce: Use whatever pasta sauce you love—marinara, meat sauce, or even crushed tomatoes with your own seasonings. Just aim for 3 to 4 cups of sauce total.
• Fresh herbs: If you don’t have fresh parsley or basil, 1 tsp dried Italian seasoning mixed into the sauce works great.

This lasagna is a full meal on its own, but you can easily add simple sides like:

• Classic Caesar salad or mixed greens
• Garlic bread to soak up every yummy bite
• Crusty Italian bread with butter and garlic powder (or make this 2-ingredient cottage cheese flatbread and brush it with garlic butter)
• Roasted veggies like zucchini or broccoli

How to Store and Freeze

Refrigerate: Leftover crockpot lasagna keeps beautifully in the fridge for up to 4 days. Just cover tightly with foil or store in airtight containers. Honestly, it tastes even better the next day when all those flavors get cozy together!

Freeze: This lasagna freezes wonderfully for up to 3 months. Cut into portions, wrap individually with plastic wrap, then pop into freezer bags for easy reheating later. You can even freeze the whole dish—just wrap super tightly to avoid freezer burn. If youre stocking the freezer with more easy meals, soups like Easy Taco Soup freeze and reheat especially well.

Reheat: To warm leftovers, cover with foil and bake at 350°F for 20-30 minutes until hot. For single servings, microwave on medium for 2-3 minutes works great. Frozen portions should thaw overnight in the fridge for the best results.

Troubleshooting and FAQs

Q: Do I have to boil the lasagna noodles first? A: Nope! This recipe is designed for uncooked noodles. The water plus sauce inside the crockpot steams and cooks them perfectly. If you only have no-boil noodles, add an extra 1/4 cup water to help them cook all the way through.

Q: What size slow cooker should I use? A: A 5–7 quart slow cooker works best for these amounts. Smaller slow cookers will be tight, and larger ones might dry out the edges or cook faster.

Q: Can I use a different protein instead of beef? A: Yes! Ground turkey, chicken, or Italian sausage all work well. If you use pre-seasoned sausage, cut back on salt to avoid over-salting. If you’re craving a cheesy chicken bake with Italian flavors instead, try our High Protein Chicken Parmesan Casserole.

Q: Can I make this vegetarian? A: Absolutely. Swap the meat sauce for a hearty vegetable sauce with sautéed mushrooms, zucchini, eggplant, spinach, or lentils. You might want a bit more sauce to keep the noodles moist.

Q: How do I avoid soggy or crunchy noodles? A: Keep your noodle layers thin and even by breaking noodles to fit, don’t skip the 1/2 cup water, and don’t lift the lid while cooking. These tips keep noodles cooking evenly. Prefer to skip noodles altogether? 30-Min Ground Beef Zucchini Boats deliver similar saucy, cheese-topped comfort without pasta.

Q: Will the top get browned like oven lasagna? A: The slow cooker won’t brown the top. If you want that golden crunch, move the cooked lasagna to a baking dish and broil for 2-4 minutes, watching closely so it doesn’t burn.

Q: How long do leftovers last and how do I reheat? A: Store leftovers in the fridge for up to 4 days or freeze up to 3 months. Reheat covered in a 350°F oven for about 20-30 minutes. The microwave works well for single portions—just heat for 2-3 minutes on medium power. Frozen pieces should thaw overnight first.

Q: Can I assemble the crockpot lasagna a day ahead? A: Yes, you can put it together in the slow cooker, cover it, and keep it in the fridge for up to 24 hours before cooking. Cooking time might be a little longer if you start from chilled, so check that noodles are tender before serving.

Q: Is it safe to leave the crockpot on when I’m out? A: Slow cookers are meant for unattended cooking for the times suggested here (3 hours high or 6 hours low). Just follow your slow cooker’s safety guidelines and don’t leave it running much longer than the recipe calls for.

Q: Will using lower-fat cheeses or different cheeses change the texture? A: Yes, lower-fat cheeses can make it less creamy. Feel free to swap mozzarella for provolone or an Italian cheese blend, plus add some Parmesan if you like. Just keep the total cheese around 2 cups to get the right texture and flavor.
