How to Make

Making this Spinach Ricotta Slow Cooker Lasagna is simple and requires minimal effort. You’ll layer the ingredients in your slow cooker, set it, and forget it while the lasagna cooks to perfection. Here’s how to do it:

Step-by-Step Instructions:

1. Prepare the Ingredients:
   • Start by chopping the fresh spinach if you’re using fresh. If you’re using frozen spinach, ensure it is thoroughly thawed and drained to remove excess moisture.
   • Grate the mozzarella cheese and Parmesan cheese.
   • Finely chop the onion and garlic.
2. Sauté the Onion and Garlic:
   • In a skillet, heat the olive oil over medium heat. Add the chopped onion and garlic. Sauté for about 3-4 minutes until they are soft and fragrant. Season with a pinch of salt, pepper, oregano, and basil. Remove from heat and set aside.
3. Prepare the Ricotta Mixture:
   • In a large mixing bowl, combine the ricotta cheese, half of the mozzarella cheese, and Parmesan cheese. Add the sautéed onion and garlic mixture and stir until everything is well combined. If you like a more seasoned filling, feel free to add a little extra salt, pepper, or herbs.
4. Assemble the Lasagna:
   • Lightly grease the bottom and sides of the slow cooker with cooking spray or olive oil.
   • Start by spreading a thin layer of marinara sauce at the bottom of the slow cooker.
   • Next, layer the no-boil lasagna noodles on top of the sauce, breaking them if necessary to fit the shape of the slow cooker.
   • Spread a layer of the ricotta mixture over the noodles, followed by a generous layer of chopped spinach (you can also layer spinach directly on top of the ricotta).
   • Repeat the layers: sauce, noodles, ricotta mixture, spinach, and continue until all ingredients are used up. Finish with a layer of marinara sauce and top with the remaining mozzarella cheese.
5. Cook the Lasagna:
   • Cover the slow cooker and set it to cook on low heat for 4-5 hours or high heat for 2-3 hours. You’ll know the lasagna is ready when the noodles are tender, and the cheese is melted and bubbly.
   • If you want a crispier top, you can uncover the slow cooker during the last 15-20 minutes of cooking to allow the cheese to brown slightly.
6. Serve and Enjoy:
   • Once cooked, allow the lasagna to cool for a few minutes before serving. This helps the layers set and makes it easier to slice.
   • Garnish with fresh basil or parsley for an extra touch of flavor and color.

Serving and Storage Tips for Spinach Ricotta Slow Cooker Lasagna

Now that you’ve made your delicious Spinach Ricotta Slow Cooker Lasagna, it’s important to know how to serve and store it for the best flavor and longevity.

Serving Tips:

• Serve with a side salad: A simple green salad with a tangy vinaigrette is the perfect side dish to balance the richness of the lasagna.
• Pair with garlic bread: For an added treat, serve your lasagna with some homemade garlic bread or crusty bread for dipping in any leftover sauce.
• Perfect for leftovers: This lasagna can be even more flavorful the next day as the flavors have time to meld together. It’s an excellent dish to make ahead for dinner parties or meal prep for the week.

Storage Tips:

• Refrigeration: Allow the lasagna to cool completely before refrigerating. Store leftovers in an airtight container in the refrigerator for up to 3-4 days.
• Freezing: This lasagna is freezer-friendly! To freeze, wrap individual portions tightly in plastic wrap and then place them in a freezer-safe bag or container. It can be frozen for up to 2-3 months. To reheat, simply thaw overnight in the refrigerator and heat in the oven at 350°F for 20-25 minutes until heated through.
• Reheating: If reheating individual portions, microwave them covered with a damp paper towel for 2-3 minutes until hot. If reheating a whole lasagna, bake in the oven at 350°F for 25-30 minutes, covering with foil to prevent the top from burning.

Mistakes to Avoid for Spinach Ricotta Slow Cooker Lasagna

While making Spinach Ricotta Slow Cooker Lasagna is quite easy, there are a few common mistakes that can affect the texture or flavor of the dish. Here are some tips on how to avoid them:

1. Not Draining the Spinach Well:

One of the most common issues people face when making spinach lasagna is excess moisture from the spinach, which can result in a watery lasagna. If you’re using fresh spinach, be sure to sauté it well to release some of the water. If you’re using frozen spinach, make sure to thaw it completely and squeeze out as much liquid as possible before adding it to the lasagna.

2. Using Regular Lasagna Noodles Instead of No-Boil Noodles:

No-boil noodles are a time-saver and are specifically designed for slow cooking. They absorb moisture as they cook, which is important in a slow cooker where there isn’t as much liquid evaporation. If you use regular lasagna noodles, they may not cook properly, leading to a chewy, undercooked texture. Stick with no-boil noodles for the best results.

3. Overfilling the Slow Cooker:

While it’s tempting to pack your slow cooker to the brim, it’s important to follow the layering instructions. Overfilling the cooker can lead to uneven cooking and might cause the lasagna to spill over. Ensure you leave some space at the top for the lasagna to expand and for proper heat circulation.

4. Skipping the Layer of Sauce at the Bottom:

Don’t skip the bottom layer of marinara sauce! This step helps prevent the lasagna noodles from sticking to the slow cooker and ensures the base is flavorful. Without this layer, the noodles may dry out or become stuck to the bottom.

5. Not Letting the Lasagna Rest Before Serving:

After the lasagna is done cooking, it’s tempting to dive right in. However, letting it rest for 10-15 minutes allows the layers to set and makes it easier to slice. If you serve it immediately, it might fall apart and lose its structure.

Tips and Tricks for Spinach Ricotta Slow Cooker Lasagna

Now that we’ve covered the mistakes to avoid, here are some tips and tricks to help you elevate your Spinach Ricotta Slow Cooker Lasagna and ensure it turns out perfect every time:

1. Add Extra Veggies:

While spinach is the main vegetable in this lasagna, feel free to get creative and add other veggies for extra flavor and nutrients. Chopped zucchini, mushrooms, or even bell peppers can be layered in between the noodles for added texture and taste.

2. Enhance the Flavor of the Sauce:

To take your marinara sauce to the next level, add a pinch of sugar to balance out the acidity, or throw in some crushed red pepper flakes for a little heat. You can also stir in a teaspoon of balsamic vinegar to add a subtle depth of flavor.

3. Use Fresh Herbs:

For a burst of fresh flavor, top your lasagna with fresh basil or parsley before serving. This simple step makes the dish look more vibrant and adds a refreshing contrast to the rich, cheesy lasagna.

4. Experiment with Different Cheeses:

Although ricotta, mozzarella, and Parmesan are the classic choices, don’t hesitate to experiment with other cheeses like provolone, gouda, or even a sprinkle of feta for a unique twist. These cheeses will melt beautifully and bring new layers of flavor to your lasagna.

5. Make It Ahead of Time:

You can prepare this lasagna ahead of time and store it in the fridge for up to 24 hours before cooking. This is perfect for busy days when you know you’ll want a hot, comforting meal ready to go. Just assemble the lasagna in the slow cooker, cover, and refrigerate until you’re ready to cook.

Suggestions

If you’re looking to get even more creative with your Spinach Ricotta Slow Cooker Lasagna, here are a few suggestions to customize the recipe to suit your tastes or dietary preferences:

1. Make It Gluten-Free:

For those following a gluten-free diet, you can swap out the regular lasagna noodles for gluten-free alternatives. There are many gluten-free pasta options available that will work just as well in this recipe. Make sure to check the cooking instructions on the pasta package as gluten-free noodles may need slightly different cooking times.

2. Add a Protein:

If you’d like to add some extra protein to your lasagna, consider including cooked ground chicken, turkey, or even plant-based protein like lentils or crumbled tofu. These ingredients can be layered between the noodles for a more hearty, filling meal. Simply sauté the meat or protein before adding it to the layers of the lasagna.

3. Vegan-Friendly Version:

For a vegan version of this dish, you can easily swap the ricotta and mozzarella cheeses with plant-based alternatives. There are many dairy-free cheese options made from cashews, almonds, or soy. You can also make a cashew ricotta at home by blending soaked cashews with lemon juice, garlic, and nutritional yeast to mimic the flavor of ricotta cheese.

4. Make It Spicy:

For those who enjoy a little heat, you can add red pepper flakes, hot sauce, or even a spicy sausage to the lasagna for an extra kick. Layering these spicy elements will give your dish a bold flavor that’s sure to please those who love spice.

5. Serve with a Side Salad:

While lasagna is hearty on its own, pairing it with a simple side salad can help balance out the richness of the dish. A fresh, light salad with a tangy vinaigrette will complement the flavors of the lasagna without overpowering it. You could also serve it with a side of garlic bread for an even more comforting meal.
