We love lasagna in our house! Lasagna, when done correctly, can take 90 minutes-2 hours to make. Usually, I don’t have that kind of time, but that doesn’t mean I have to give up making lasagna! This Gluten Free Lasagna with Polenta and Vegetables is the perfect, quick and easy recipe – ready in under 45 minutes and just as satisfying as the traditional version!

I love this twist on the traditional version of lasagna. Fresh, sliced polenta replaces the noodles, a mix of shredded cheeses make it rich but not too heavy, and seasonal veggies cooked with Italian spices add texture and flavor to this recipe. I was originally inspired by this recipe from EatingWell, but modified it significantly to make it even more flavorful and healthy — to appeal to meat-eaters, picky-eaters, vegetarians and gluten-free diets alike!

Gluten Free Lasagna with Polenta and Vegetables

This recipe makes 8 HUGE servings, and it’s a wonderful balanced meal with the fiber and healthy goodness from the veggies, the protein from the cheese, and the whole grains from the polenta.

It also makes for amazing leftovers, and will last in the fridge for up to 4 days!

How To Make This Gluten Free Lasagna – Step By Step

Step 1: Preheat oven to 450 degree F. Coat a 9-by-13-inch baking dish with cooking spray. Heat oil in a large nonstick skillet over medium-high heat. Add onion, red pepper, zucchini, garlic, salt and pepper, Italian seasoning and crushed red pepper and cook, stirring occasionally, until the vegetables are tender and just beginning to brown, 4 to 6 minutes.

Is Polenta Healthy For You?

The short answer is, yes! Polenta is made from cornmeal – so if you’re using organic polenta it is a great gluten-free alternative in many recipes. Other than being gluten-free, polenta has a number of health benefits including:

  • High in fiber
  • A good source of complex carbs, making it low glycemic. This means it’s broken down more slowly and takes longer to digest, keeping your blood sugar levels steady.
  • Rich in Vitamin A and C, and a good source of carotenoids

Is this polenta and garden vegetable lasagna kid-friendly?

You might be surprised, but yes it is! The combination of the cheese, creamy polenta and fragrant spices makes this a dish that the whole family (picky kids included) will love. If you have an especially picky eater who can’t stand looking at a vegetable, I recommend chopping up the veggies in this dish super super small so that they blend into the sauce and aren’t very noticeable. You can even use a food processor to finely chop the veggies to make it easier to “hide” them in the dish 🙂

What does Polenta taste like?

Polenta is made from ground yellow corn and is super mild in flavor. I’d say that polenta tastes like a coarser version of grits. One of the great things about polenta is that it tends to take on the flavor of anything it’s mixed with – which makes it the perfect gluten-free substitute for lasagna noodles in this dish!

How do you use cooked polenta?

While you can make polenta from scratch at home, there are wonderful pre-cooked varieties (that come in the shape of a tube) available in the grocery store. This “tubed” version is what I used in this dish – and it’s a great option for any kind of layering dish.

You can use cooked polenta as a substitute for gluten-free pasta noodles (like I did here), as part of a Mexican casserole for some corn flavor, fried up like mini pancakes as part of a breakfast, grilled alongside other ingredients, or even cut up into fries and baked!

Top Tips For This Gluten Free Lasagna

  • Use a pasta sauce that is all natural with no added sugar.
  • You can use any kind of shredded cheese you like in this recipe. I opted for sharper parmesan, but mozzarella or goat cheese would taste fabulous as well!
  • This is a great “clean out your fridge” recipe. If you don’t have the veggies I used, you can use just about any vegetable in this recipe and it will work great!
  • If you need to make this ahead of time, assemble everything the day before and refrigerate — unbaked and covered — for up to 24 hours.
  • Let stand for 15 minutes before cutting and serving.
