If you are looking to make some changes or add your own twist to this delicious Portabella Mushroom with Spinach and Feta Lasagna recipe, there are plenty of substitutions and variations that you can try.

Firstly, if you don’t have any portabella mushrooms on hand, you can substitute them with regular mushrooms. You can use either white button mushrooms or cremini mushrooms. They may not be as flavorful as portobello mushrooms but they will still do the job.

For a vegan option, replace the egg with mashed tofu, chickpea flour or aquafaba. Additionally, use vegan cheese alternatives like Miyoko’s mozzarella-style cheese shreds, Follow Your Heart feta crumbles or homemade cashew cheese to replace the feta and mozzarella cheese in this recipe.

If you need to cut down on calories or want to make this lasagna gluten-free, use thinly sliced zucchini or eggplant instead of lasagna noodles. It’s a great alternative for people who are on a low-carb diet.

For those who love spice, add some chopped jalapeños or red pepper flakes to the tomato sauce mixture. If you prefer a creamy consistency to the sauce, use ricotta cheese instead of cottage cheese or goat cheese.

Lastly, try adding extra vegetables like sliced bell peppers or sun-dried tomatoes for additional flavor and texture. You can also incorporate cooked quinoa or lentils for an added protein source.

Are you planning to make this delicious Portabella Mushroom with Spinach and Feta Lasagna for a special occasion or just want to have leftovers for the week? Here’s how you can make-ahead, store and reheat this wonderful vegetarian dish.

To Make-Ahead:

If you’re prepping this dish ahead of time, I recommend baking it until it’s almost fully cooked. Then, allow it to cool completely and cover tightly with aluminum foil or plastic wrap. Place it in the fridge for up to 24 hours.

When ready to serve, let the lasagna come to room temperature for about 30 minutes before reheating in the oven.

To Store:

If you have leftovers, store them in an airtight container and refrigerate for up to 3 days. You can also freeze the lasagna for up to 3 months! For best results, I suggest freezing individual portions so that you can easily thaw what you need.

To Reheat:

If reheating a slice or two of lasagna: Preheat your oven at 375°F. Place the lasagna in an oven-safe dish and cover it loosely with aluminum foil. Bake for 15-20 minutes, or until heated through.

If reheating an entire lasagna: Preheat the oven at 375°F. Cover the lasagna with aluminum foil and bake for 45-60 minutes if frozen, or 30-40 minutes if refrigerated.

Pro-tip: To prevent overcooking, remove the foil during the last few minutes of baking so that the cheese can brown and bubble.

This wonderful vegetarian dish is perfect for meal prepping or feeding a crowd. Just make sure you follow these easy steps for make-ahead, storing and reheating all while still maintaining the flavor of this wholesome recipe.

Tips for Perfect Results

Cooking is an art, and sometimes even the simplest of recipe can present a challenge. If you want to make the perfect Portabella Mushroom with Spinach and Feta Lasagna, there are a few tips that can help you. Here are some suggestions for getting this wonderful vegetarian dish desired by everyone.

Firstly, make sure to use fresh spinach instead of frozen whenever possible. Fresh spinach has more flavor and texture, which makes it ideal for this dish. Frozen spinach can be used, but it will not result in the same quality of taste.

Another tip is to cook the mushrooms before baking them in the lasagna. This will bring out their flavor and reduce their moisture content, which will prevent the lasagna from becoming watery or soggy.

If you want to elevate your dish even further, consider adding sundried tomatoes or goat cheese to your lasagne. These ingredients add a unique flavor that complements the earthiness of the portobello mushroom and the tanginess of the feta cheese.

Furthermore, when layering your lasagne, use cottage cheese instead of traditional ricotta cheese. Cottage cheese is lower in fat and calories than ricotta cheese, making it a healthier option. It also has a lighter texture that complements the spinach and portobello mushrooms well.

Lastly, do not overcook your lasagna noodles before assembling them in the dish. Overcooked noodles can become too soft and can fall apart easily when baked.

These tips might seem small, but they can make all the difference in creating a delicious lasagna that everyone will enjoy.
