Ingredients

Scale

Meat and Vegetables

  • 1 teaspoon avocado oil or olive oil
  • 1 lb lean ground beef (90-93% lean)
  • ½ medium yellow onion, diced finely (¾ cup)
  • 5 garlic cloves, minced (~1 ½ tablespoons)
  • 3 ounces fresh spinach (2 large handfuls), roughly chopped

Seasonings and Sauces

  • 2 teaspoons dried Italian seasoning
  • ½ teaspoon fine salt
  • ¼ teaspoon black pepper
  • 1 (24-ounce) jar marinara sauce
  • 1 ½ cups water

Pasta and Cheese

  • 8 ounces uncooked lasagna noodles (not ‘No boil’ type), broken into small pieces
  • 8 ounces (2 cups) shredded mozzarella cheese, divided
  • 1 cup cottage cheese, lightly drained
  • ⅓ cup shredded Parmesan cheese

Garnish

  • Fresh basil leaves, optional for garnish


Instructions

  1. Cook the Meat Mixture: Place a large skillet over medium-high heat and spray it generously with cooking spray. Add the ground beef, diced onion, minced garlic, Italian seasoning, salt, and pepper. Break up the meat using a spoon or spatula and cook for 8-10 minutes, stirring occasionally, until the beef is fully cooked and onions have softened. Drain excess fat if there is a lot.
  2. Prepare the Slow Cooker Base: Spray the slow cooker insert with cooking spray. Transfer the cooked beef and vegetable mixture to the bottom of the slow cooker.
  3. Add Sauce, Noodles, and Cheese: Add marinara sauce, water, chopped spinach, broken lasagna noodles, and 1 ½ cups shredded mozzarella cheese to the slow cooker. Stir gently to combine all ingredients evenly.
  4. Add Cottage Cheese: Dollop the drained cottage cheese over the top of the mixture. Gently fold it into the mixture without fully mixing to maintain texture.
  5. Top with Remaining Cheese and Cook: Sprinkle the remaining mozzarella cheese (about ½ to ¾ cup) and shredded Parmesan cheese evenly over the top. Cover and cook on LOW for 3-4 hours, or until the noodles are tender.
  6. Serve and Garnish: Once cooked, turn off the slow cooker. Garnish with fresh basil leaves and additional Parmesan cheese if desired. Serve warm.

Notes

  • This lasagna cooks entirely in the slow cooker, making it convenient for busy schedules and easy to prepare ahead.
  • Use uncooked lasagna noodles broken into smaller pieces to ensure even cooking in the slow cooker.
  • Lightly drain cottage cheese to prevent excess moisture in the final dish.
  • Optional fresh basil garnish adds a bright, fresh flavor at serving.
  • Make sure to not over-stir after adding the cottage cheese to preserve layers and texture.
