Portobello Mushroom Burgers

Instructions

1. Thoroughly rinse fresh produce under warm running water for 20 seconds. Scrub to remove excess dirt.
2. Preheat oven to 350 degrees. Coat a baking sheet with cooking spray.
3. Heat a large skillet over medium-low heat. Add 1 tablespoon olive oil and onion. Sauté onion until soft. Add garlic, mushrooms, and red pepper flakes. Season with salt and pepper to taste. Cook until mushrooms are brown, 5 to 8 minutes. Remove skillet from heat and transfer mushroom mixture to a large bowl to cool, at least 10 minutes.
4. Add panko, breadcrumbs, carrots, lentils, and herbs to mushroom mixture. Season to taste with salt and pepper. Add eggs and stir to combine. Divide mixture into 8 patties.
5. Reheat skillet over medium-low heat. Add the remaining 2 tablespoons olive oil. Cook each patty until golden brown, 3 to 4 minutes per side.
6. Transfer patties to prepared baking sheet. Bake until cooked through, about 10 minutes. Internal temperature of patties should be 145 degrees using an instant-read thermometer. Serve warm.
