What You’ll Need for the Copycat Red Robin Black & Bleu Burger

- 4 quarter-pound hamburger patties (or make your own with ground beef)
- 4 ounces baby portobello mushrooms, sliced (substitute with white mushrooms if needed)
- ½ small onion, sliced thin (yellow or white onions work best)
- 1 Tablespoon butter (unsalted preferred)
- 4 hamburger buns (we recommend brioche buns for a soft, buttery texture)
- Garlic aioli, for topping (store-bought or homemade)
- Lettuce, for topping (romaine or iceberg for crunch)
- Bleu cheese crumbles, for topping (adjust to taste)
How to Make the Perfect Copycat Black & Bleu Burger
- Cook the hamburgers: Prepare the hamburger patties using your preferred method (grill, stovetop, or broiler). Cook to your desired doneness (medium-rare: 130°F, medium: 140°F, well-done: 160°F).
- Sauté the mushrooms and onions: While the burgers cook, heat a skillet over medium heat. Add the butter, sliced mushrooms, and onions. Cook for 8-10 minutes, stirring occasionally, until the mushrooms are browned and the onions are caramelized and soft.
- Assemble the burgers: Spread a generous layer of garlic aioli on the bottom half of each bun. Top with a piece of lettuce, followed by a cooked hamburger patty. Add a spoonful of the sautéed mushrooms and onions, then sprinkle with bleu cheese crumbles.
- Serve and enjoy: Place the top bun over the assembled burger and serve immediately. Pair with fries or a side salad for a complete meal!
Elevate Your Burger with Sauces and Toppings
While the garlic aioli and bleu cheese crumbles are stars of this recipe, don’t hesitate to experiment! Try adding a drizzle of balsamic glaze for a tangy twist or swap the aioli for a spicy chipotle mayo. For extra crunch, add a handful of crispy fried onions or bacon bits. These small tweaks can make your burger even more irresistible!
Perfect Pairings: What to Serve with Your Burger
This hearty burger pairs beautifully with classic sides like steak fries or sweet potato fries. For a lighter option, serve it with a crisp side salad or coleslaw. Don’t forget a cold beverage—think craft beer or iced tea—to complete the meal!
Time-Saving Tips for Busy Cooks
Short on time? Use pre-sliced mushrooms and pre-made garlic aioli to cut down on prep. You can also cook the burgers and sauté the mushrooms and onions simultaneously in separate pans to save time. For an even quicker option, grill the patties outdoors while the veggies cook indoors!
How to Store and Reheat Leftovers
If you have leftover burgers, store the components separately to maintain freshness. Keep the patties, mushrooms, and onions in airtight containers in the fridge for up to 2 days. To reheat, warm the patties and veggies in a skillet over medium heat until heated through. Assemble with fresh buns and toppings for the best texture.
Recipe Variations to Try
Switch things up by using ground turkey or chicken patties for a lighter version. Vegetarian? Try a portobello mushroom cap as the patty substitute. For a different cheese, swap bleu cheese for gorgonzola or feta. These variations keep the recipe exciting and adaptable to your preferences!
