A low carb way to enjoy all the yumminess of lasagna
Place the portobello mushroom caps on a lined baking sheet. Brush with olive oil and sprinkle with kosher salt and pepper. Place in a 400 degree oven for 10 minutes.
As the mushrooms cook, put the Italian sausage in a skillet over medium heat. Cook 5-8 minutes, breaking it apart as it cooks.
Let the mushrooms cool slightly. Spread ricotta cheese on each mushroom. Top with the cooked sausage, then spoon the marinara sauce over the sausage. Top each with the mozzarella cheese. Place the baking sheet back into the 400 degree oven for an additional 10-12 minutes.
Serve with fresh basil for garnish if desired.
