FAQ
Vegetable Lasagna Recipe Substitutions and Variations
- Lasagna noodles: If you’re short on time or need a healthier option, you can switch out the regular noodles for some whole wheat or gluten-free ones.
- Zucchini: Yellow squash works just as good if you cant find zucchini at your local store.
- Button mushrooms: You can easily use cremini or portobello mushrooms to bring a different flavor without changing the texture too much.
- Ricotta cheese: Cottage cheese is a great substitute if you wanna lighten things up or if you cant get ricotta.
- Marinara sauce: Feel free to mix up your own tomato based sauce with garlic, basil and tomato paste if you dont have ready-made marinara.
Pro Tips
1. When you’re boiling the noodles, keep an eye on them coz if they get too soft they might fall apart when you layer the lasagna later.
2. Try giving the veggies a quick roast in the oven for about 10 minutes before adding them to the dish. It can really boost their flavors and make the lasagna tastier.
3. For extra creamy and flavorful layers, mix a bit more marinara in with the ricotta cheese than what the recipe suggests. It helps the cheese spread easier and gives a nice blend of taste.
4. Don’t be in a rush to dig in once it comes out of the oven. Let the lasagna rest for a few minutes so the layers settle. That way its easier to slice and you don’t lose all your hard work.
