Roast beef reaches 145°F (63°C) for medium-rare doneness. Caramelized onions take 30 minutes over low heat to develop sweetness.
Slider buns toast best at 350°F (175°C) for 5 minutes to avoid sogginess.
Au jus should be simmered until it reduces to a thick glaze for maximum flavor.
Use a meat thermometer to avoid undercooking the beef.
Caramelized onions may burn if not stirred occasionally.
Slider buns can be substituted with brioche or sourdough.
Roast beef can be pre-sliced for faster assembly.
About the Ingredients
1 (3-pound) beef roast
Choose a well-marbled cut for juiciness. Substitute with thinly sliced deli meat if short on time.
6 slider buns
Use brioche or sourdough for better texture. Gluten-free buns work for dietary needs.
1 large onion, thinly sliced
Red onions add color and mild tang. Use shallots for a more delicate flavor.
1/4 cup (30g) brown sugar
Adds sweetness to the onions. Substitute with maple syrup for a different flavor note.
2 tbsp (30ml) olive oil
Coats onions evenly. Use butter for a richer caramelization.
1 cup (240ml) beef broth
Used to make au jus. Chicken broth works if beef is unavailable.
1 tbsp (15g) Worcestershire sauce
Enhances umami. Substitute with soy sauce for a saltier alternative.
1/2 tsp (2.5g) garlic powder
Adds depth without overpowering. Fresh garlic can be used if preferred.
1/4 tsp (1g) black pepper
Balances sweetness. Use cayenne for a spicy kick.
1/2 cup (120ml) melted butter
Optional for basting. Use olive oil if avoiding dairy.
