Ingredients

Units Scale

Meat Sauce

  • 1 lb extra-lean ground beef
  • 1 yellow onion, diced
  • 2 cloves garlic, minced
  • 1/2 tsp salt
  • 1/2 tsp pepper
  • 1 (650 mL) jar tomato sauce

Lasagna Layers

  • 1 lb lasagna noodles (uncooked, oven-ready or regular)
  • 1 (475 g) tub ricotta cheese
  • 2 cups mozzarella cheese, divided
  • 1 (650 mL) additional jar tomato sauce
  • 1/2 cup water

Garnish

  • Chopped fresh basil or parsley
  • Cooking spray (for slow cooker)

Instructions

  1. Brown the beef: In a large frying pan over medium-high heat, brown 1 lb extra-lean ground beef until almost cooked through, about 5-7 minutes.
  2. Add aromatics and sauce: Add diced yellow onion, minced garlic, salt, pepper, and 1 jar (650 mL) of tomato sauce to the beef. Stir well and cook until onions soften and beef is fully cooked, about 3-4 minutes.
  3. Prepare slow cooker: Spray the slow cooker insert with cooking spray to prevent sticking.
  4. Layer the lasagna: Spread a bit of the meat sauce on the bottom of the slow cooker. Add a layer of uncooked lasagna noodles, breaking pieces to fit if necessary. Dollop ricotta cheese and sprinkle some mozzarella over noodles, then add more meat sauce. Repeat layering 3 times total, finishing with meat sauce.
  5. Add top layer and water: Pour the second jar (650 mL) of tomato sauce evenly over the top layer. Sprinkle remaining mozzarella cheese on top. Pour 1/2 cup water around the edges inside the slow cooker to help the noodles cook evenly.
  6. Cook the lasagna: Cover and cook on high for 3 hours or on low for 6 hours until noodles are tender and cheese is melted and bubbly.
  7. Garnish and serve: Let the lasagna rest for about 10 minutes. Garnish with fresh chopped basil or parsley, then cut and serve warm.

Notes

  • This recipe is perfect for busy days as it requires minimal prep and cooks hands-off in the slow cooker.
  • Breaking the noodles to fit the slow cooker helps achieve even layering.
  • Use oven-ready noodles for convenience or regular noodles for a softer texture.
  • Leftover lasagna freezes well—store in airtight containers and reheat thoroughly.
  • Adding water around the edges helps prevent dryness and ensures the noodles cook properly.
