Cauliflower Lasagna — Do This Next

Ready to create this delicious dish? Follow these steps for a successful outcome:
1. Cook the Noodles
Begin by boiling a large pot of salted water. Add the whole wheat lasagna noodles and cook according to the package directions. Once done, drain and set aside.
2. Prepare the Cauliflower
While the noodles are cooking, chop the head of cauliflower into smaller florets. Rinse thoroughly and set aside.
3. Sauté the Vegetables
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes. Then, add the sliced mushrooms and cook for an additional 4-5 minutes until they are tender. Remove from heat and set aside.
4. Make the Cauliflower Sauce
In a medium saucepan, add the cauliflower florets and cover with water. Bring to a boil and cook until the cauliflower is tender, about 10-12 minutes. Drain and transfer to a blender. Add the low-fat milk, whole wheat flour, onion powder, and a pinch of salt and pepper. Blend until smooth and creamy.
5. Assemble the Lasagna
Preheat your oven to 350°F (175°C). In a greased baking dish, layer the cooked lasagna noodles, followed by a portion of the sautéed mushroom and onion mixture, and then a generous layer of the cauliflower sauce. Repeat the layers, finishing with a layer of cauliflower sauce on top.
6. Add the Cheese
Sprinkle the freshly grated Parmesan cheese over the top layer of sauce. Make sure to distribute it evenly for a beautifully melted, cheesy finish.
7. Bake
Cover the baking dish with foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the top is golden and bubbly.
8. Let It Rest
Once out of the oven, let the Cauliflower Lasagna rest for about 10 minutes before slicing. This will help the layers set and make serving easier.
