When preparing this recipe, you might need to visit the supermarket for a few specific items. Gluten-free lasagna noodles are essential and can usually be found in the gluten-free section.

Ingredients for Gluten-Free Lasagna Casserole Slow Cooker Recipe
Ground turkey or ground beef: Choose either ground turkey or ground beef based on your preference for a leaner or richer flavor.
Marinara sauce: A jar of marinara sauce provides the tomato base for the meat sauce.
Ricotta cheese: This creamy cheese adds richness to the layers.
Mozzarella cheese: Shredded mozzarella melts beautifully and adds a gooey texture.
Parmesan cheese: Grated parmesan adds a sharp, salty flavor to the cheese mixture.
Gluten-free lasagna noodles: These noodles are essential for keeping the dish gluten-free.

Technique Tip for This Recipe
When layering the lasagna noodles in the slow cooker, make sure to slightly overlap the edges to ensure they cook evenly. This will help prevent any undercooked or overly crunchy pieces. Additionally, if you find that your gluten-free noodles are particularly thick, consider soaking them in warm water for a few minutes before layering to ensure they become tender during the cooking process.

How to Store / Freeze This Dish
- Allow the lasagna casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
- Transfer the cooled lasagna to an airtight container. If you have a large batch, consider dividing it into smaller portions for easier reheating.
- Store the container in the refrigerator if you plan to consume the lasagna within 3-4 days. For longer storage, place it in the freezer.
- When freezing, wrap the container with an additional layer of aluminum foil or plastic wrap to prevent freezer burn.
- Label the container with the date and contents to keep track of its freshness.
- To reheat refrigerated lasagna, preheat your oven to 350°F (175°C). Place the lasagna in an oven-safe dish, cover with foil, and bake for about 20-25 minutes or until heated through.
- For frozen lasagna, thaw it in the refrigerator overnight before reheating. Alternatively, you can reheat it directly from frozen by baking at 350°F (175°C) for 45-60 minutes, covered with foil, until hot and bubbly.
- If you prefer using a microwave, transfer a portion of lasagna to a microwave-safe dish, cover, and heat on medium power in 1-2 minute intervals, stirring occasionally, until thoroughly heated.
- For an added touch, sprinkle some extra mozzarella cheese on top before reheating to achieve a fresh, melty finish.
- Enjoy your reheated gluten-free lasagna casserole with a side of garlic bread or a fresh salad for a complete meal.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover lasagna in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes or until heated through. For a crispy top, remove the foil during the last 5 minutes of baking.
Microwave Method: Place a portion of the lasagna on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. If needed, continue heating in 30-second intervals until hot.
Stovetop Method: Heat a non-stick skillet over medium-low heat. Add a splash of water or marinara sauce to the skillet to prevent sticking. Place the lasagna in the skillet, cover with a lid, and heat for about 10-15 minutes, turning occasionally to ensure even heating.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the lasagna in the air fryer basket, ensuring it is not overcrowded. Heat for about 5-7 minutes or until warmed through, checking halfway to prevent overcooking.
Slow Cooker Method: If you have time, you can reheat the lasagna in the slow cooker. Place the lasagna back in the slow cooker, cover, and heat on low for 1-2 hours or until heated through. This method is great for maintaining the dish's moisture and texture.
