Ingredients

Ground Beef (1 lb, 80/20 blend recommended):
- Why it’s important: Provides a juicy, flavorful base for the patties.
- Substitutions: Ground turkey, chicken, or plant-based meat for vegetarian (adjust cooking time slightly for leaner meats).
Bacon (4 slices, ~½ cup cooked):
- Why it’s important: Adds smoky, crispy texture and flavor.
- Substitutions: Turkey bacon, pancetta, or omit for vegetarian (add ½ tsp smoked paprika for smoky flavor).
Large Onion (1, sliced, ~2 cups):

- Substitutions: Yellow onion, shallots, or 1 tsp onion powder (mixed with sauce).
Irish Stout (½ cup, such as Guinness):
- Why it’s important: Infuses the onions with rich, malty flavor.
- Substitutions: Non-alcoholic stout, beef broth, or cola with 1 tsp molasses.
Cheddar Cheese (½ cup, grated):
- Why it’s important: Melts into a gooey, sharp topping for the patties.
- Substitutions: Irish cheddar, Colby, or vegan cheddar.
Sour Cream (½ cup):
- Why it’s important: Creates a creamy, tangy base for the sauce.
- Substitutions: Greek yogurt, crème fraîche, or vegan sour cream.
Dijon Mustard (2 tbsp):

Worcestershire Sauce (1 tbsp):
- Why it’s important: Enhances umami and savory flavor in the patties.

Black Pepper (to taste, about ½ tsp):

- Substitutions: White pepper or a pinch of cayenne.
Burger Buns (4, preferably brioche):
- Why it’s important: Provides a soft, slightly sweet base for the burger.
- Substitutions: Potato buns, gluten-free buns, or lettuce wraps for low-carb.
Butter (2 tbsp, for toasting buns):
- Why it’s important: Adds richness and crispiness to the buns.
- Substitutions: Olive oil or vegan butter.

Additional for Slow Cooker:

Olive Oil (1 tbsp, for searing):
- Why it’s important: Used to sear patties for a flavorful crust.
- Substitutions: Vegetable oil or cooking spray.
Beef or Vegetable Broth (¼ cup):
- Why it’s important: Keeps the patties moist during slow cooking.

Instructions

Step 1: Cook the Bacon and Caramelize the Onions

In a large skillet over medium heat, cook 4 slices bacon until crispy, about 5–7 minutes. Remove and place on paper towels to drain, reserving 1 tbsp bacon grease in the skillet.
Add 1 sliced large onion to the skillet with the reserved grease and cook over medium-low heat for 10–15 minutes, stirring occasionally, until soft and caramelized.
Pour in ½ cup Irish stout (e.g., Guinness) and simmer for 5–7 minutes until the liquid reduces by half. Season with ¼ tsp salt and ¼ tsp black pepper, then set aside.
Tip: Slice onions thinly for faster caramelization, and stir frequently to prevent burning. Add a pinch of sugar if onions need extra sweetness.

Step 2: Prepare and Sear the Burger Patties

In a large bowl, combine 1 lb ground beef with 1 tbsp Worcestershire sauce, ½ tsp salt, and ¼ tsp black pepper. Mix gently to avoid overworking the meat.
Form into 4 equal patties, slightly larger than the buns (~4 inches wide), making a slight indentation in the center to prevent puffing during cooking.
Heat a skillet or grill pan over medium-high heat with 1 tbsp olive oil. Sear the patties for 2–3 minutes per side to develop a golden crust but not fully cook through (the slow cooker will finish cooking).
Tip: Sear in batches if needed to avoid overcrowding, and press patties lightly to ensure even browning.

Step 3: Assemble in the Slow Cooker

Lightly grease the slow cooker insert with cooking spray or a thin layer of oil to prevent sticking.
Place the seared patties in a single layer in the slow cooker. Pour ¼ cup beef or vegetable broth around (not over) the patties to maintain moisture without softening the crust.
Spoon the caramelized Guinness onions evenly over the patties to infuse flavor during cooking.
Tip: Place a small rack or crumpled foil balls under the patties to elevate them slightly, keeping the crust intact.

Step 4: Slow Cook

Cover and cook on low for 4–5 hours or high for 2–3 hours, until the patties are cooked through (160°F/71°C internally for medium).
In the last 10 minutes of cooking, sprinkle ½ cup grated cheddar cheese over the patties, cover, and let it melt.
Check doneness early with a meat thermometer to avoid overcooking, as slow cookers vary.
Tip: If excess liquid accumulates, carefully drain some before serving to keep the patties firm.

Step 5: Prepare the Sauce and Toast the Buns

In a small bowl, mix ½ cup sour cream, 2 tbsp Dijon mustard, and a pinch of salt until smooth. Set aside or refrigerate until ready to serve.
In a skillet over medium heat, melt 2 tbsp butter. Toast 4 brioche buns, cut side down, for 1–2 minutes until golden brown. Alternatively, toast in a 350°F (175°C) oven for 3–5 minutes.
Tip: Spread butter evenly on buns for consistent toasting, and keep toasted buns warm under a clean towel until assembly.

Step 6: Assemble and Serve

Place a cheese-topped patty with caramelized onions on the bottom half of each toasted bun.
Add 1 slice of crispy bacon (broken in half) on top of each patty.
Spoon a generous dollop of the sour cream-Dijon sauce (~2 tbsp) over the bacon, letting it drip slightly.
Top with the bun lid and serve immediately with fries, potato chips, or a side salad.
Tip: Serve with extra sauce on the side for dipping, and provide napkins for the juicy, saucy burgers.
