Ingredients

• 4 pieces Large Portobello mushroom caps
• 2 tablespoons Olive oil
• 1 pound Ground beef (80% lean)
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 teaspoon Garlic powder
• 0.5 teaspoon Onion powder
• 0.25 teaspoon Smoked paprika
• 4 slices Cheddar cheese slices
• 4 pieces Lettuce leaves
• 4 slices Tomato slices
• 4 tablespoons Mayonnaise
• 1 medium Avocado
• 1 teaspoon Lemon juice
• 8 leaves Fresh basil leaves

Directions

Step 1

Preheat the oven to 400°F (200°C).

Step 2

Gently clean the Portobello mushroom caps with a damp paper towel and remove the stems.

Step 3

Brush both sides of the mushroom caps with 1 tablespoon olive oil and place them on a baking sheet, gill side up.

Step 4

Bake the mushrooms in the preheated oven for 8-10 minutes until slightly tender. Remove and set aside.

Step 5

In a mixing bowl, combine the ground beef, salt, black pepper, garlic powder, onion powder, and smoked paprika. Mix until well combined.

Step 6

Divide the beef mixture into four equal portions and shape each into a patty.

Step 7

Heat a large skillet or grill pan over medium-high heat and add the remaining tablespoon of olive oil.

Step 8

Cook the beef patties for about 3-4 minutes on each side or until they've reached desired doneness. During the last minute of cooking, place a slice of cheddar cheese on top of each patty and cover to melt the cheese.

Step 9

While the patties are cooking, mash the avocado in a small bowl and mix in the lemon juice to make avocado spread.

Step 10

Assemble the burger by spreading 1 tablespoon of mayonnaise on the gill side of one mushroom cap, place a lettuce leaf, a tomato slice, a beef patty with melted cheese, some avocado spread, two basil leaves, and top with another mushroom cap.

Step 11

Repeat the assembly for the remaining burgers.

Step 12

Serve immediately and enjoy your gourmet low carb mushroom burgers!
