1. Heat olive oil in a large skillet over medium heat. Add chopped onions and sauté until soft, about 3-4 minutes. Stir in garlic and cook for 1 minute more. Add brisket to the skillet, searing both sides until browned, about 2-3 minutes per side.

2. Pour in beef broth, maple syrup, tomato paste, soy sauce, black pepper, smoked paprika, and salt. Stir well to combine and bring to a gentle simmer.

3. Cover the skillet, reduce heat to low, and simmer for 2-3 hours or until brisket is tender and shreds easily. Check occasionally and add a splash of broth if needed. Once done, shred the brisket using two forks and coat in the sauce.

4. To create the ideal waffle base for your Brisket Grilled Cheese Waffle Burgers, start by whisking together the dry ingredients – flour, baking powder, and salt – in a large bowl. In a separate bowl, whisk the wet ingredients – eggs, milk, melted butter, and sugar (if using). Gently fold the wet mixture into the dry ingredients until just combined, being careful not to overmix.

5. Heat up your waffle iron and cook the batter according to the manufacturer’s instructions, typically 3-5 minutes per waffle. The result should be a waffle that’s crisp on the outside and tender on the inside, providing the perfect foundation for your brisket and melted cheese.

6. To build your Brisket Grilled Cheese Waffle Burgers, start by placing one cooked waffle on a plate. Top it with a generous helping of the shredded, saucy brisket, followed by a layer of shredded cheddar or gouda cheese. If you’d like to add some extra flavor and texture, consider topping the brisket with sliced pickles, sautéed onions, or a handful of baby arugula. Top it off with a second waffle to complete your delectable sandwich.

7. Heat a skillet or griddle over medium-low heat and carefully place the assembled sandwich on the surface. Gently press down on the top waffle to help the cheese melt and the waffle get a nice, golden-brown crust. Cook for 2-3 minutes per side, or until the cheese is melted and the waffles are crispy.

8. Serve your piping hot Brisket Grilled Cheese Waffle Burgers with your favorite dipping sauce, such as barbecue, honey mustard, or even a creamy horseradish sauce. A fresh, crunchy salad or a side of crispy fries would also make the perfect accompaniment to this indulgent, flavor-packed creation.
