Ingredients
Instructions
- Preheat your oven to 425°F. Cut the potatoes into 1/2-inch thick wedges. Toss with a drizzle of oil, half the fry seasoning, salt and pepper. Spread on a baking sheet and roast for 20-25 minutes, flipping halfway, until golden and crispy.
- While potatoes roast, cook the bacon in a skillet over medium heat until crispy, about 6-8 minutes. Transfer to a paper towel-lined plate. Reserve 1 tablespoon of bacon fat in the skillet.
- Thinly slice the onion. Add to the skillet with the bacon fat and cook over medium-low heat, stirring occasionally, until deeply caramelized, about 15-20 minutes. Strip the thyme leaves and stir in half the leaves during the last 2 minutes. Season with salt and pepper.
- In a small bowl, combine the cream sauce base, beef stock concentrate and 1/4 cup water. Stir until smooth. Set aside.
- Form the ground beef into two patties, each about 1/2-inch thick. Season generously with salt and pepper. Heat a grill or skillet over medium-high heat. Cook patties for 4-5 minutes per side for medium or to your desired doneness. In the last minute, top each patty with mozzarella cheese and cover to melt.
- Slice the brioche buns in half and toast them lightly on the grill or in a toaster. Halve the lemon. Squeeze the juice of one half into a bowl with the mixed greens, a drizzle of oil, salt and pepper. Toss to coat. Slice the tomato into rounds.
- To assemble, spread a spoonful of the cream sauce mixture on the bottom bun. Place a patty, then top with caramelized onions, crispy bacon and tomato slices. Add the top bun. Serve with potato wedges and lemon-dressed salad on the side.
Recipe Tips
For extra crispy bacon, cook it in the oven on a rack over a baking sheet at 400°F for 15-20 minutes.
Caramelizing onions takes patience; cook low and slow for the best flavor.
If you don’t have fry seasoning, substitute with a mix of paprika, garlic powder and onion powder.
FAQ
Can I use a different cheese instead of mozzarella?
Yes, provolone or Swiss cheese would work well, as they melt nicely and complement the flavors.
Can I make the potato wedges ahead of time?
Yes, you can roast them up to an hour ahead and reheat in a hot oven for a few minutes before serving.
Is there a substitute for the cream sauce base?
You can use a mixture of 1/4 cup heavy cream and 1/4 cup beef broth thickened with a teaspoon of flour.
