Step-by-Step Instructions
Preparation of Tofu Ricotta
Start by making the tofu ricotta. Take one block of firm tofu and drain it well. Place the tofu in a food processor. Add 1/4 cup of nutritional yeast, 2 minced garlic cloves, and 1 tablespoon of fresh lemon juice. Then, add 1 teaspoon of dried oregano, 1 teaspoon of dried basil, and a pinch of salt and pepper. Blend everything until smooth and creamy. Taste the mixture and adjust the seasoning if needed. Set this tasty ricotta aside for later.
Layering the Lasagna in the Slow Cooker
Now, let's layer our lasagna. Begin by spreading a thin layer of marinara sauce on the bottom of your slow cooker. This helps prevent sticking. Lay 3 lasagna noodles horizontally over the sauce. On top of the noodles, add half of the sliced zucchini, half of the sliced mushrooms, and half of the diced red bell pepper. Then, layer half of the fresh baby spinach. Spoon half of your prepared tofu ricotta over these veggies. Repeat this process with another layer of sauce, 3 noodles, the rest of the vegetables, spinach, and the remaining ricotta. Finally, top it all with 3 more noodles and the rest of the marinara sauce.
Cooking Times and Techniques
Cover the slow cooker with its lid. Set it to low and cook for 4 to 6 hours. The noodles should be tender, and the sauce should be bubbling. In the last 30 minutes, check the top layer. If it looks a bit dry, add a little extra marinara for moisture. For a cheesy flavor, you can sprinkle a bit of nutritional yeast on top. After cooking, turn off the slow cooker and let the lasagna rest for about 10 minutes. This will help with slicing. Enjoy your hearty meal!
