Method
- Caramelize the onions: Heat 2 Tbsp olive oil or butter in a large skillet over medium-low heat. Add sliced onions and about 1 tsp Kinder's Caramelized Onion Butter Seasoning. Cook slowly, stirring occasionally, 15–20 minutes until deeply golden, soft, and sweet. If they start sticking, add a splash of water. Remove from heat and set aside.
- Form the patties: Divide ground beef into 4 equal portions (about ½ lb each). Gently shape into patties slightly wider than the buns — they shrink as they cook. Press a small thumb indent in the center to prevent puffing. Season both sides generously with Kinder's Caramelized Onion Butter Seasoning.
- Heat your cooking surface: Heat a flattop, cast-iron skillet, or griddle over medium-high until very hot. Lightly oil if needed.
- Cook the burgers: Place patties on the hot surface and cook 4–5 minutes per side for medium (internal temp 140–145°F), or to your preferred doneness. In the last 1–2 minutes, top each patty with a slice of cheese and cover briefly to melt.
- Toast the buns: While burgers finish, toast buns cut-side down on the cooking surface 1–2 minutes until golden and warm.
- Rest: Remove patties to a plate and rest 2–3 minutes.
- Build: Spread Kinder's BBQ Sauce on the bottom bun. Add lettuce, the cheesy patty, a generous mound of caramelized onions, another drizzle of BBQ sauce, then the top bun. Serve immediately.

Notes
- Low and slow on the onions — Medium-low heat is non-negotiable. High heat gives you soft, gray onions; medium-low gives you deep golden with real sweetness. Don't rush the 15–20 minutes.
- Deglaze when they stick — A splash of water or a small drizzle of balsamic vinegar lifts the fond and adds quiet complexity without redirecting the flavor.
- Cheese choice matters — Provolone or Swiss melts smooth and mild, keeping the caramelized onion front. White cheddar sharpens the profile. Pick based on what you want to lead.
- Thumb indent = flat patty — Press a small indentation in the center of each patty before it hits the pan. It counteracts shrinkage and prevents the dome effect that throws off even cooking.
- Smash option — For lacy, crunchy edges and a juicy center, smash each patty thin on a screaming-hot flattop with wax paper and firm pressure. Different texture, same seasoning.
- Make-ahead onions — Caramelize up to 2 days ahead and refrigerate. Reheat in a skillet with a pat of butter before building. This is the move for cookouts.
- Crispy shoestring fries are the obvious call — the thin crunch contrasts the soft, golden onions and gives the plate texture. Thick-cut steak fries work too if you want something more substantial. Either way, don't overthink the side.
- A cold, creamy coleslaw cuts through the richness of the beef and butter-seasoned onions. Doesn't need to be fancy — basic cabbage, a sharp dressing, something cool and acidic. That contrast does real work.
- For presentation: slice the burger in half and serve it open-faced on a wooden board. The cross-section shows the layers — golden onions, melted cheese, seared patty — and it makes a strong table impression. Kinder's BBQ sauce on the side for dipping rounds it out.
- Cooked patties keep in the fridge up to 3 days in an airtight container. Store the caramelized onions separately — they hold up to 5 days and are worth making in a larger batch.
- To reheat patties: hot skillet, 2–3 minutes per side, or a 325°F oven for 10 minutes loosely covered with foil. Avoid the microwave — it steams out the crust and softens the texture. Reheat onions in a small skillet with a pat of butter over medium-low.
- Always assemble fresh. Toasted bun, fresh lettuce, patty and onions reheated separately. Pre-assembled burgers go soggy fast.
