Prep & Cook Time
- Prep Time: 15 minutes
- Cook Time: 180 minutes (3 hours)
- Total Time: 3 hours 15 minutes
- Servings: 10
Ingredients
- 1½ pounds ground beef
- 2 tbsp Italian seasoning (divided in half)
- 24 ounce can roasted garlic herb spaghetti sauce
- 1 cup beef broth
- 2½ cups shredded mozzarella cheese (divided (you’ll need a 16 ounce bag or 16 ounce block))
- 2½ cups small curd cottage cheese ((you’ll need a 24 ounce tub))
- 1 large egg
- 12 lasagna noodles (NOT NO-BOIL) (uncooked)
- Fresh minced parsley ( optional garnish)
Instructions
- In a large skillet over medium-high heat, brown the ground beef until no longer pink. Drain any excess fat. Stir in half (1 tablespoon) of the Italian seasoning.
- To the skillet with the beef, add the entire jar of roasted garlic herb spaghetti sauce and the beef broth. Stir until well combined and let it simmer for 2-3 minutes. Remove from heat.
- In a medium bowl, mix the cottage cheese, egg, and the remaining 1 tablespoon of Italian seasoning until fully combined.
- Spread about 1 cup of the meat sauce mixture in the bottom of a 6-quart or larger slow cooker.
- Break 3-4 lasagna noodles to fit in a single layer over the sauce, covering as much area as possible.
- Spread ⅓ of the cottage cheese mixture over the noodles, then sprinkle with ⅓ of the shredded mozzarella cheese. Spoon ⅓ of the remaining meat sauce over the cheese.
- Repeat the layering process (noodles, cottage cheese, mozzarella, meat sauce) two more times, for a total of three layers.
- For the final top layer, after the last layer of meat sauce, sprinkle the remaining mozzarella cheese over everything.
- Turn off the slow cooker, remove the lid, and let the lasagna rest for 15-20 minutes before serving. Garnish with fresh parsley if desired.
Variations
- Meat Lover’s: Before adding the final cheese layer, sprinkle cooked and crumbled Italian sausage or pepperoni over the top sauce.
- Vegetable Boost: Add a layer of thawed and well-drained frozen spinach or thinly sliced zucchini between the noodle and cheese layers.
- Creamier Version: Substitute half of the cottage cheese with an equal amount of ricotta cheese for a richer texture.
- Single-Serve Style: Layer the ingredients in smaller, greased oven-safe dishes placed inside the slow cooker for individually portioned lasagnas.
Tips for Success
- Letting the lasagna rest after cooking is crucial; it allows the layers to set for cleaner slices.
- Break the noodles to fit your slow cooker’s shape, ensuring they don’t overlap too thickly in the center for even cooking.
- If your slow cooker tends to run hot, check for doneness at the 2.5-hour mark to prevent the noodles from becoming mushy.
Storage & Reheating
Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, place individual portions in the microwave until warmed through, or cover a baking dish with foil and reheat in a 350°F oven for 15-20 minutes.
FAQ
1. Can I cook this on HIGH instead of LOW?
It’s not recommended. Cooking on LOW for 3 hours allows the noodles to become tender without burning the edges or making the dish watery. The high, direct heat of the HIGH setting often leads to overcooked noodles and a scorched bottom.
2. Do I really need to break the noodles?
Yes, breaking the noodles to fit the shape of your slow cooker is important for creating even layers and ensuring the noodles cook uniformly. Whole noodles will leave large gaps or create overly thick spots.
3. Why can’t I use no-boil noodles?
No-boil noodles are designed to absorb a specific amount of moisture in a dry oven environment. In the moist, steamy slow cooker, they absorb too much liquid and can turn the lasagna into a mushy, starchy mess.
4. My lasagna seems watery after cooking. What happened?
This is usually due to not letting it rest. The resting period allows the noodles to fully absorb the liquid and the layers to set. If it’s still too wet, your slow cooker may not vent steam properly; next time, try placing a clean kitchen towel under the lid to catch condensation.
5. Can I substitute the cottage cheese?
Yes, you can use an equal amount of full-fat ricotta cheese for a more traditional flavor and texture. The cottage cheese provides a lighter, slightly tangier result.
6. Can I prepare this lasagna ahead of time?
You can assemble the layers in the slow cooker insert up to a day in advance, cover it tightly, and refrigerate. When ready to cook, you may need to add an extra 15-30 minutes to the cooking time since you’re starting with a cold insert.
