Blue Cheese Burgers with Crispy Fried Onion, Made Easy

Step 1: Prepare the Onions
Start by heating a large skillet over medium heat. Add the 2 tablespoons of butter and let it melt. Once melted, toss in the sliced onions, seasoning them with 1 teaspoon of salt and 1 teaspoon of pepper. Cook the onions, stirring occasionally, until they are golden brown and crispy, about 10-15 minutes. Remove them from the skillet and set aside.
Step 2: Cook the Burger Patties
In the same skillet, add the burger patties. Cook them to your desired doneness, about 4-5 minutes per side for medium, depending on thickness. In the last minute of cooking, place a slice of blue cheese on each patty, allowing it to melt slightly.
Step 3: Toast the Buns
While the burgers are cooking, slice the burger buns in half and toast them lightly on a separate skillet or in the oven until golden brown. This adds an extra layer of flavor and prevents them from getting soggy.
Step 4: Assemble Your Burgers
Now it’s time to assemble! Spread 1 tablespoon of sweet and spicy mustard on the bottom half of each toasted bun. Layer with baby arugula or baby kale, followed by the burger patty topped with melted blue cheese. Add fresh tomato slices and finish with a generous portion of crispy fried onions. Cap it off with the top half of the bun.
Step 5: Serve and Enjoy
Serve your Blue Cheese Burgers with Crispy Fried Onion immediately while they are hot and juicy. Pair them with your favorite sides like sweet potato fries or a fresh salad for a complete meal.
Holiday-Friendly Variations

- BBQ Blue Cheese Burger: Brush the patties with barbecue sauce while cooking for a smoky flavor.
- Mushroom Swiss Variation: Swap blue cheese for sautéed mushrooms and Swiss cheese for a different twist.
- Spicy Jalapeño Burger: Add sliced jalapeños on top of the blue cheese for a spicy kick.
- Veggie Burger Option: Use a hearty vegetable or bean-based patty for a delicious plant-based version.
Steer Clear of These
While making your Blue Cheese Burgers with Crispy Fried Onion, there are a few things to avoid:
- Overcooking the burgers: Use a meat thermometer to check for doneness. Aim for 160°F for beef patties.
- Skipping the toasting step: Toasting the buns adds texture and flavor, so don’t skip it!
- Using low-quality blue cheese: Choose a good quality blue cheese for the best flavor.
- Neglecting seasoning: Don’t forget to season the patties and onions adequately. Taste as you go!
Storage Pro Tips
To keep your Blue Cheese Burgers with Crispy Fried Onion fresh:
- Store leftover patties in an airtight container in the refrigerator for up to 3 days.
- Fried onions can be kept crispy by storing them in a separate container at room temperature.
- Reheat burgers in the microwave or skillet, adding more cheese if desired for an extra melty topping.
- Assemble the burgers fresh rather than storing them fully assembled to maintain texture.
