Ingredients

• 3 tablespoons olive oil , divided, or more as needed
• 1.5 tablespoons garlic flavored olive oil
• ¼ onion , cut into chunks
• 2 portobellos mushroom caps , sliced
• salt and black pepper to taste
• freshly grated Parmesan
• freshly grated Asiago cheese

Instructions

1. 1 Gather the ingredients.
2. 2 Warm 1 1/2 tablespoons olive oil and garlic-flavored olive oil together in a skillet over medium heat until fragrant, about 1 minute. Stir in onions and mushrooms; reduce heat to low, and cook until the mixture has softened and caramelized, with browning around the edges, 8 to 12 minutes, adding additional olive oil if needed to prevent sticking.
3. 3 Turn off heat, drizzle with remaining 1 1/2 tablespoons olive oil, and season with salt and pepper. Sprinkle generously with Parmesan and Asiago cheeses.
