Healthy Roasted Veggie Lasagna – Gluten Free!

Lasagna isn’t usually synonymous with healthy. Conversely, you may only consider lasagna for a special occasion or “cheat” meal. That’s not the case in our house. Because this lasagna comes loaded with nutritious vegetables, minimal cheese, and is packed full of protein, we have lasagna at least once a month.

Did I mention this lasagna is high in protein? Noodles have come a long way from being a nutrient-lacking, fast-burning carb. You can now get a variety of noodles made from a variety of high-protein ingredients, such as, red lentils, chickpeas, edamame, black beans and more!

For this recipe, use the Explore Cuisine Organic Green Lentil Lasagne Noodles. These don’t require boiling beforehand, are certified Gluten Free, and a 2 oz serving has 11 grams of protein.

Ingredients for Roasted Lasagna, included crushed tomatoes and Organic Green Lentil Pasta

From start to finish this dish takes just about an hour, but aside from cutting and assembly most of that time is cooking time. This recipe also works great with store-bought pasta sauce, but I prefer making my own as per the recipe below. The sauce recipe was inspired by Primavera Kitchen. I just add more spices to mine. I highly recommend her Spinach and Lasagna Recipe.

Green Zucchini, Red Bell Peppers, Broccoli and half an onion for Roasted Lasagna


Start by slicing the zucchini and roasted red pepper into thin slices. Slice the zucchini lengthwise. I used to leave the bell pepper in large flat pieces, but I found cutting them into thin rings works better for assembly and eating!

While the vegetables are roasting, start the sauce. This will need to simmer for about 25 minutes to really get the flavors to pop. The vegetables will finish roasting before the sauce is done. Take them out of the oven and set aside to cool for easier assembly.

Begin the layers with a little sauce in the bottom of the pan. This will prevent sticking. Place a layer of the green lentil noodles first, followed by a layer of zucchini, sauce, and then cheese. Add another layer of noodles.

Next, add the layer of red bell peppers – there is only one. Add sauce and cheese to the red pepper layer. Repeat with the zucchini layer. Finish with sauce and cheese on top.

Cook uncovered for 25-30 minutes. Remove from oven and let cool for 10 minutes. Serve with your favorite veggie side. I love to pan sauté broccolini.
