Traditional lasagna uses lasagna noodles which are high in carbs. This recipe swaps the noodles for sliced zucchini to keep it low carb. The zucchini slices cook down and mimic the texture of lasagna noodles.

How to cook lasagna in a slow cooker

Cooking lasagna in a slow cooker is a great hands-off way to make this classic baked pasta dish. Here are some tips for slow cooker lasagna success:

Use a slow cooker liner or foil sling to make removal easy. Spray the liner with non-stick cooking spray before assembling the lasagna. Start with a layer of your favorite jarred pasta sauce on the bottom. Add a layer of uncooked lasagna noodles, breaking them to fit. Top with ricotta cheese mixture, mozzarella slices, and meat sauce. Repeat the layers until your slow cooker is full, ending with sauce and mozzarella.

Make sure to spread the sauce and fillings all the way to the edges so the noodles cook evenly. Pour a cup of water along the edges to help create steam. Cook on low for 4-6 hours until the pasta is tender and the cheese is melted and bubbly.

Allow the lasagna to rest for 10-15 minutes before serving. Use the foil sling or liner to carefully lift the lasagna out of the slow cooker fully intact. Slice and serve with garlic bread or salad. Leftover lasagna can be refrigerated for 3-4 days or frozen for up to 3 months.

Avoiding Excess Liquid in Crock Pot Low Carb Lasagna

Excess liquid is a common issue when making lasagna in the slow cooker. The moist environment can make the lasagna watery instead of nicely layered and cohesive. Here are some tips to help avoid excess liquid in your crock pot low carb lasagna:

  • Use zucchini, eggplant or cooked squash instead of noodles – Fresh veggies release less moisture than uncooked noodles.
  • Pat meat and vegetables dry – Drain and blot ground meat, mushrooms, spinach and other veggies with paper towels after cooking to remove excess moisture.
  • Use cottage or ricotta cheese – They tend to be drier than moist shredded mozzarella.
  • Place paper towels between layers – Lay paper towels over the zucchini or vegetable noodles to absorb extra moisture.
  • Cook on low heat setting – The lower temperature helps prevent boiling and overflow.
  • Don’t overfill – Leave at least 1 inch of headspace for ingredients to bubble as they cook.
  • Let cool before serving – Allow the lasagna to rest 20-30 minutes before cutting so excess liquid can absorb back into the dish.

With these tips, you can enjoy perfectly layered low carb lasagna with tomatoes, meat and cheese that slice cleanly without any watery drips. Avoid the liquid issue with veggies instead of noodles, blotted meats, paper towel layers and proper slow cooker technique.

How to Store and Reheat This Lasagna

One of the best parts about slow cooker lasagna is enjoying the delicious leftovers for days after. Here are some tips for storing and reheating your crock pot lasagna:

  • Let lasagna cool completely – Don’t cover or refrigerate until lasagna has cooled to room temperature to prevent condensation.
  • Store in airtight container – Place cooled lasagna in a tightly sealed glass or plastic container. Plastic wrap can also work for short term storage.
  • Refrigerate up to 4 days – Keeps well refrigerated for 3-4 days. Freeze for longer storage.
  • Reheat individual portions – Slice desired amount of lasagna and reheat on a plate in the microwave or oven.
  • Microwave carefully – Microwave single servings on Medium power in 30 second increments until hot.
  • Oven reheat at 350°F – Place lasagna slices on a baking sheet and cover with foil. Heat at 350°F for 15-20 minutes.
  • Add moisture – If lasagna seems dry, add a splash of marinara sauce or a sprinkle of water before reheating.
  • Avoid sogginess – Don’t overheat or lasagna may become soggy. Just warm until heated through.

With proper storage and reheating, you can enjoy your crock pot lasagna for lunches or quick dinners throughout the week. The key is letting it cool completely before storing and reheating individual slices as needed.
