Ingredients: 6 clean Portabella Mushroom caps; 1 15-ounce container of whole milk ricotta cheese mixed with 2 tablespoons chopped Italian parsley, 1 teaspoon granulated garlic powder a pinch of salt and pepper; 1 or 2 cooked meatballs of crushed or loose-cooked Italian sausage (or mix both together, around 1/2 cup); extra virgin olive oil for drizzling or cooking oil spray; granulated garlic powder enough for each cap; oregano is optional we like it sprinkled evenly on each cap; 1/4 cup of grated Pecorino Romano Cheese or Parmesan grated cheese; 1 cup of your favorite pizza sauce or marinara sauce; freshly torn basil leaves; slices of provolone (non-smoked) cheese one for each cap or use whole milk mozzarella; optional: you can add a pinch of fennel seed for a sausage flavor if you don't have any sausage to add

Lasagna Stuffed Portabello Mushrooms are a delicious baked stuffed extra large mushroom cap that can be an appetizer or a whole meal layer with everything but the pasta!

Of course, mushroom lovers are going to be astounded by this all-in-one meal, and the substitutions and fillings can be endless on whatever you like in your pasta lasagna.

We chose to go with a layer of ricotta, tomato sauce, crushed meatballs, and/or sausage topped with lots of mozzarella and provolone blended and grated cheese.

Although you're very familiar with the traditional lasagna, we use the meaty-tasting portabello as a substitute.

When it comes to lasagna, every family makes it different, so adapted the filling to however you're used to making it.

Mom always used ricotta in our lasagna, but you can also substitute cottage cheese if that's what you prefer!

If you have a mushroom lover in your crowd, not a meat lover, keep it all vegetarian by adding spinach or artichoke hearts.

Whatever you decide, our recipe card below for stuffed lasagna-style portabello is just a guideline for you to follow and just get your own spin on this dish.

Portabello Mushrooms Low Carb Friendly

Portobello mushrooms, also sometimes called portabella, are rich in flavor, and their texture is meatier and less spongy than button mushrooms.

When you've cleaned and scooped out the gills, you have a nice vessel for stuffing, and perfect for low-calorie diets instead of pasta carbs so these are diabetic-friendly.

The skies are the limit, there are many suggestions below for you to choose from for stuffing your mushroom caps.

Cleaning Portobello Mushrooms

Some folks say not to wash them because of moisture content, I rinse them in water and use a paper towel to clean any residue off(I do not like bugs, dirt so sometimes if they are terribly dirty I will soak them in hot water regardless but you can do your own methods on what you are comfortable eating)
Holding a mushroom in one hand, use a spoon to gently scrape the gills from the underside of the portobello mushroom cap; discard the gills
I use my DIY seasoning salt (just pick your favorite kind of seasoning or use my Italian blends)
Always season the mushrooms caps before they bake in the oven lightly you can add more later if they aren't salty enough for your taste buds
The filling you're using whether you combine vegetables, spinach leaves, or sliced pepperoni needs to be chopped into small pieces so it fits nicely in the cavity.
