Why You'll Love This Recipe

  • It's creamy...and savory...and bursting with cheesy deliciousness. (Is that a word?) Anyway, you get the picture.
  • Serve Portobello Chicken Lasagna with Rainbow Salad and crusty bread. Date night will never be the same again.
  • It's also the perfect portobello mushroom pasta for any night of the week!

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 another type, but trust me on this...baby bella mushrooms 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.

In a separate large skillet 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.

If you've never used no-boil lasagna noodles, you're in for a treat. You just pop them in a dish and they miraculously cook in the sauce. Genius.

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.

Recipe FAQS

Can I use substitute type of mushroom?

You can, but portobello mushrooms are perfect for this recipe. They're hearty enough to hold up to the sauce and baking process.

Is there a substitute for teriyaki sauce?

Yes, if you prefer not to use teriyaki sauce, you can use white wine instead. The flavor will be a little different, but it will still taste delicious.

Can I add garlic cloves or fresh herbs?

Absolutely! Minced garlic and fresh parsley or fresh thyme tastes amazing in this dish.
