What Type of Mushrooms Should I Use?

Portobello mushrooms are meatier in texture and hold up well in the creamy alfredo sauce that binds this lasagna together. You could use other mushrooms, but trust me on this…baby bellas are worth the difference.

It’s also important to grate the parmesan by hand in this recipe or your sauce will be grainy (and who wants that?) So, it takes a little effort on the back end, but you’ll be glad you took this extra step.

How to Make Portobello Chicken Lasagna

Start by collecting all of your ingredients. You’ll need butter, portobello mushrooms, onion, teriyaki sauce, (ad) rotisserie chicken, heavy cream, dried Italian seasoning, minced garlic, pepper, parmesan cheese, mozzarella cheese, and no-boil lasagna noodles. (ad)

If you’ve never used no-boil lasagna noodles, you’re in for a treat. I consider them a secret weapon of sorts. You just pop them in a dish and they miraculously cook in the sauce. Genius.

Step by Step Instructions

Melt a tablespoon of butter in your cast iron skillet, (ad) then add diced onions and sliced portobellos. Sauté for 5 minutes until mushrooms are tender. Add 1/4 cup teriyaki sauce (ad) and 2 cups of cubed rotisserie chicken. Stir it up, then set aside and keep warm.

In a separate skillet (ad) or pot, melt butter over medium low heat. Add cream and allow to simmer for 3 minutes. Stir in garlic, pepper and Italian seasoning, cooking for another minute or two. Add parmesan cheese (shredded by hand) and stir until creamy.

Now, the magic begins. Combine the alfredo sauce with the chicken mixture to make the filling. Spoon a little of the filling in an 11 X 8 inch casserole dish, then sprinkle some of the mozzarella on top.

Cover the mixture with slices of lasagna noodles, (ad) then repeat the process at least two more times until you end with mozzarella cheese on top. Yum! Portobello Chicken Lasagna!

Sprinkle the entire dish with dried parsley and bake in a 350 degree oven for 40 minutes until golden brown and bubbly.
