Begin by heating a skillet over medium heat. Add a drizzle of oil and toss in the finely chopped onions. Sauté them until they’re translucent, about 5 minutes. The aroma will fill your kitchen and make your mouth water.

Next, add the ground beef to the skillet. Break it up with a spatula while it browns. Ensure there’s no pink left and cook until it’s nicely browned. This step seals in the flavors.

Now, sprinkle in the smoked paprika. This adds a subtle depth to your mixture. Give it a good stir to mix the beef and onion well. Trust me, the savory smell at this stage is heavenly.

Go ahead and add the drained diced tomatoes. These not only add flavor but also moisture. Stir them in, letting them break up a bit as you mix.

Pour in the barbecue sauce, beef stock, ketchup, and Worcestershire sauce. Stir everything together until it’s well combined. Let this simmer for about 10 minutes. This is where the magic starts to happen. Watch the sauce become thick and luscious.

While the beef mixture is simmering, lightly toast your brioche buns. A little crunch will help to hold the sloppy filling without making a mess.

Now, time to assemble! Spoon a generous amount of the beef mixture onto the bottom half of each bun. Top it with shredded cheddar cheese. Place the top bun over it, and voila—you’re ready to dig in!
