Crockpot Lasagna Ingredients
Gathering these simple components always feels like setting the stage for something wonderful. Combining beef, rich tomatoes, and salty cheeses creates perfect Italian-American harmony inside your slow cooker. These basic building blocks transform into something spectacular. Now, let’s quickly look at what each part contributes before we dive deeper. Remember, precise measurements wait for you on the card below.
- Ground Beef or Italian Sausage: Provides the hearty, savory base flavor for the meat sauce.
- Onion and Garlic: These form the aromatic backbone, adding essential savory depth.
- Crushed Tomatoes, Tomato Sauce, Paste: These form the liquid foundation for a flavorful, thick ragu.
- Ricotta Cheese: This guarantees that soft, billowy layer of creamy texture.
- Egg: It binds the ricotta mixture so it stays perfectly intact during cooking.
- Lasagna Noodles: They absorb the sauce beautifully, becoming tender without pre-boiling.
- Mozzarella and Parmesan Cheeses: These melt into that glorious, bubbly, cheesy topping we all adore.
Substitutions and Tips
Feel free to sneak in finely chopped carrots or celery with your onions for added nutrition. If you skip parsley, dried oregano works fine in a pinch. Use half ground beef and half Italian sausage for an extra flavor punch. Storing leftovers in the slow cooker insert, covered, helps keep them fresh longer. For a tangier sauce, add a dash of red wine vinegar.
How to Make Crockpot Lasagna

Making this dish is straightforward, blessedly so. We just need preparation, layering, and patience, honestly. Follow these steps closely for the best results with your slow cooker lasagna.
Step 1: Preparing the Meat Sauce
Start by browning your ground beef or sausage well. Cook the chopped onion right alongside the meat until softened. Drain off any rendered grease completely. Next, toss in the minced garlic briefly. Just cook it for one minute until the aroma blooms nicely. Don’t let the garlic burn, though.
Step 2: Simmering the Sauce Base
Now you bring everything together for that amazing sauce. Stir in the crushed tomatoes right away. Then add the tomato sauce and the thick tomato paste. Pour in the measured water to thin it slightly. Next, toss in the Italian seasoning, salt, and pepper. Bring this whole mixture to a gentle simmer briefly. Remove the sauce from the burner once it heats up.
Step 3: Mixing the Ricotta Filling
Grab a separate, medium-sized bowl for the creamy layer. Combine the ricotta cheese with the single egg well. Mix in your fresh parsley right now. Season this mixture with its own small measure of salt and pepper. Whip this together until it looks uniformly smooth and creamy.
Step 4: Layering the Slow Cooker
Ensure your slow cooker insert is nicely coated with cooking spray first. Ladle approximately one full cup of your meat sauce onto the bottom surface. Then, strategically place 3 or 4 dry lasagna noodles over that sauce layer. Break them if you need them to fit snugly. Spread half of that wonderful ricotta mixture over the noodles next. Top this with about 1.5 cups of the shredded mozzarella cheese. You need another layer of meat sauce now, about 1.5 cups worth. Keep repeating this pattern. Use the remaining noodles, sauce, and top everything finally with cheeses. Everything should be covered in the final layer of mozzarella and Parmesan.
Step 5: Cooking to Perfection
Cover your slow cooker tightly with its lid securely. Set the setting to low heat for three to four hours. Alternatively, you can cook on high for two to three hours. Look for the noodles to feel completely tender when poked gently. The cheese should be beautifully bubbly and nicely melted throughout.
Step 6: The Crucial Resting Period
This waiting step is extremely important, trust me on this one. Turn the heat off immediately when done cooking. Leave the Crockpot Lasagna covered for twenty minutes minimum. This resting time lets everything settle down. It really helps the slices hold their shape perfectly when you serve them.
How to Store Crockpot Lasagna
Cool the finished lasagna slightly before storing it away. Refrigerate leftovers promptly in an airtight container. It usually stays good for about three to four days safely. For longer storage, slice it first. Wrap individual portions tightly in plastic wrap then foil. Freeze them for up to three months easily. Thaw in the fridge overnight before reheating gently.
Tips for Success
- Use Oven-Ready Noodles: They save time usually spent boiling pasta beforehand.
- Don’t Overfill: Keep layers below the indicated max fill line on your slow cooker insert.
- Check Periodically: If using a very old cooker, check tenderness around the two-hour mark.
- Sauce Consistency Matters: Ensure your sauce is not too watery before layering begins.

- A 6-quart slow cooker is essential for this recipe.

Ingredients
- 1.5 lbs ground beef or Italian sausage
- 1 large onion, chopped
- 3 cloves garlic, minced
- 1 (28 ounce) can crushed tomatoes
- 1 (15 ounce) can tomato sauce
- 1 (6 ounce) can tomato paste
- 1/2 cup water
- 2 teaspoons dried Italian seasoning
- 1 teaspoon salt, or to taste (for sauce)
- 1/2 teaspoon black pepper, or to taste (for sauce)
- 15 ounces ricotta cheese
- 1 large egg
- 1/4 cup chopped fresh parsley
- 1/2 teaspoon salt (for ricotta)
- 1/4 teaspoon black pepper (for ricotta)
- 12 lasagna noodles, uncooked (oven-ready or regular)
- 4 cups (about 16 ounces) shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
Instructions
- In a large skillet, brown the ground beef (or sausage) and chopped onion over medium-high heat. Drain any excess grease.
- Add minced garlic and cook for 1 minute more until fragrant.
- Stir in the crushed tomatoes, tomato sauce, tomato paste, water, Italian seasoning, 1 teaspoon salt, and 1/2 teaspoon black pepper. Bring to a simmer, then remove from heat. This is your meat sauce.
- In a medium bowl, combine ricotta cheese, egg, fresh parsley, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Mix well. This is your ricotta mixture.
- Spray the inside of a 6-quart (or larger) oval or rectangular slow cooker with non-stick cooking spray.
- Spread about 1 cup of the meat sauce on the bottom of the slow cooker.
- Place 3-4 uncooked lasagna noodles over the sauce, breaking them to fit if necessary (they will overlap slightly).
- Spread half of the ricotta mixture over the noodles.
- Top with about 1.5 cups of shredded mozzarella cheese.
- Add another layer of meat sauce (about 1.5 cups).
- Repeat the noodle, ricotta, mozzarella, and meat sauce layers.
- Finish with a final layer of noodles, the remaining meat sauce, and the remaining mozzarella and Parmesan cheeses.
- Cover and cook on low for 3-4 hours, or on high for 2-3 hours, until the noodles are tender and the cheese is bubbly and melted. Cooking times can vary based on your slow cooker and noodle type (regular noodles may take longer than oven-ready).
- Once cooked, turn off the slow cooker and let the lasagna rest, covered, for 15-20 minutes before serving. This allows it to set and makes for easier slicing.
Notes
- Cooking times may vary depending on your slow cooker model and whether you use oven-ready or regular lasagna noodles.
- Letting the lasagna rest for 15-20 minutes after cooking is crucial for easier slicing.
- You can substitute Italian sausage for ground beef for a richer flavor.
