- 1 teaspoon salt: Essential for enhancing all the flavors in the dish.

Putting Together Slow Cooker Lasagna

Making Slow Cooker Lasagna is an enjoyable process that rewards you with a comforting meal at the end. Let’s dive into the steps together!
In a large skillet over medium heat, cook the Italian sausage and onion until the sausage is browned and the onion is translucent, about 5 to 7 minutes. You want to see the sausage crumbling and getting nice and golden, while the onion adds a beautiful sweetness.
Add the garlic and sauté for another minute until fragrant. You’ll notice the aroma filling your kitchen, setting the stage for a delicious meal.
Next, stir in the crushed tomatoes, tomato paste, water, salt, and oregano. Mix everything together until well incorporated. The colors should blend beautifully, creating a rich, red sauce.
Layer the bottom of your slow cooker with 1 cup of the sauce. This will prevent the noodles from sticking to the bottom.
Add a layer of lasagna noodles to fit in the pan, then spoon over a generous layer of the meat sauce mixture. You want to cover the noodles completely to ensure they cook evenly.
Next, add a layer of baby spinach, followed by dollops of ricotta cheese. The creaminess of the ricotta will seep into the layers, creating a delightful texture.
Repeat layering two more times: noodles, meat sauce, spinach, and ricotta. Don’t forget to top with any remaining sauce and finish with a generous sprinkle of mozzarella cheese on top.
Cover the slow cooker and cook on low for 3 hours. During this time, the ingredients will meld together beautifully, and the house will smell incredible.
Once cooked, let it sit for a few minutes before serving. This allows the layers to set a bit, making it easier to cut and serve. The cheese should be bubbly and golden.
Serve warm, garnished with extra parsley if desired, and enjoy every gooey, cheesy bite of your Slow Cooker Lasagna.
Things Worth Knowing
- Cooking times may vary: Depending on your slow cooker, you may need to adjust the cooking time slightly. Some cook faster than others.
- Layering technique: Make sure to fully cover the noodles with sauce to avoid any dryness or undoneness.
- Let it rest: Allowing the lasagna to sit after cooking helps the layers firm up, making it easier to slice.
- Ingredient quality matters: Using fresh ingredients can elevate the overall flavor of your lasagna.
