These are beef sliders seasoned with Adobo and spicy southwest mustard, cooked on a griddle, and finished on butter-toasted buns. Twelve patties from two pounds of ground beef means you get a full party tray in under 40 minutes. They also reheat well, which makes them worth cooking in bulk.
Why this recipe works
Two things drive the result here. First, mixing mustard directly into the meat adds moisture and a mild tang that seasons the patty all the way through — not just the surface. Second, flattening the portioned balls between two plates gives you consistent half-inch thickness across all twelve patties, so they cook evenly in the same two-minute window without guessing. Uneven patties mean some are overcooked before others hit a safe internal temperature of 160°F (71°C). Uniform thickness solves that problem before the griddle even heats up.
Smart swaps
- Adobo Seasoning: This is a salt-based blend of garlic, oregano, and turmeric. If you don’t have it, use ¾ teaspoon garlic salt plus a pinch of dried oregano — not a perfect match, but it works.
- Spicy southwest mustard: Regular yellow mustard is too mild here. A grainy Dijon with a dash of hot sauce is a closer substitute than plain yellow.
- Ground beef fat content: 80/20 is the right call for sliders this size. Leaner beef dries out fast at the two-minute cook time — skip the 90/10 even if it’s what you have on hand.
- Cheese: The recipe leaves the variety open. American melts fastest and holds through reheating better than cheddar, which can turn oily.
Common problems and fixes
- Patties puff up in the middle while cooking: This happens when the meat is overworked or the griddle isn’t hot enough before the patties go on. Make sure the surface is fully preheated and press each patty lightly with a spatula in the first 30 seconds of cooking.
- Buns burn before they brown: Butter scorches quickly if the heat isn’t turned down after removing the patties. The recipe says to turn the heat back to medium — don’t skip that step, and watch the buns closely; they only need about 60–90 seconds per side.
- Sliders fall apart when assembled: This usually means the balls were packed too loosely before flattening. Roll them firmly so there are no cracks in the surface before you press them down.
- Cheese slides off during serving: Place the cheese immediately after the flip while the patty surface is still wet with rendered fat. Waiting even 30 seconds means it won’t bond properly.
- Uneven seasoning across the batch: If you season after mixing rather than before, some patties get more than others. Add the Adobo, onion powder, pepper, and mustard before you start mixing so everything distributes evenly.
Leftovers and meal prep
Cooked patties keep in an airtight container in the fridge for up to four days. Store them separately from the buns — assembled sliders go soggy fast. To reheat, place patties in a covered skillet over medium-low heat for about two minutes per side, or microwave on a rack at 50% power in 30-second intervals until they hit 165°F (74°C) at the center. For longer storage, freeze the cooked patties in a single layer on a baking sheet, then transfer to a zip bag once solid; they’ll keep for up to three months. Thaw overnight in the fridge before reheating. The butter-toasted buns don’t freeze well, so toast fresh ones when you’re ready to serve.
Juicy Mini Burger Recipe
Ingredients
- 2 pounds ground beef
- 1 teaspoon Adobo Seasoning
- ½ teaspoon onion powder
- ½ teaspoon ground black pepper
- 1 tablespoon spicy southwest mustard
- 3 sprays cooking spray
- 12 slices cheese
- 2 tablespoons butter
- 2 tablespoons butter melted
- 12 mini slider buns
- Condiments of choice
Instructions
- Combine meat, Adobo, onion powder, pepper, and mustard. Mix with hands until just combined. Portion out and roll meat mixture into 12 balls (half mixture, next separate into fourths, then each fourth into 3 balls).
- Arrange balls on the plate. Use a second plate to flatten into 1/2 inch tall patties.
- Spray griddle with non-stick spray and preheat on Medium/Medium-High until hot. Cook the first side of the patties for 2 minutes, flip, immediately place on cheese, and cook for another 2 minutes (for well done, cook 3 minutes on each side). Set cooked patties aside.
- Turn off the heat and remove excess grease (with a paper towel). Turn the heat back to Medium and add butter. Once butter is melted, place buns in butter – inside of bun down. Brush tops with melted butter. Cook on each side until lightly browned.
- Assemble sliders and add condiments.

Common questions
Can I make the patties ahead of time and cook them later?
Yes — form the patties, layer them between sheets of parchment, and refrigerate for up to 24 hours before cooking. Beyond that, the mustard in the mix starts to break down the meat texture noticeably.
What internal temperature should these sliders reach?
Ground beef needs to hit 160°F (71°C) at the center — use an instant-read thermometer to check. The two-minute-per-side timing in the recipe is a guideline, but thickness and griddle temperature vary, so the thermometer is the reliable check.
Can I cook these on a regular skillet instead of a griddle?
A large cast-iron or stainless skillet works fine. You’ll likely need to cook in two batches since a standard 12-inch pan won’t hold all twelve patties at once — crowding drops the surface temperature and causes steaming instead of searing.
How do I keep the sliders warm for a crowd without drying them out?
Place the assembled sliders in a baking dish, cover tightly with foil, and hold in a 200°F (93°C) oven for up to 30 minutes. Longer than that and the buns start to steam through and the patties tighten up.
Can I double the batch without changing anything?
Doubling the ingredients works without any adjustments to seasoning ratios or cook times. The only practical change is that you’ll need to cook in more rounds on the griddle — don’t pile extra patties on to rush it, or they won’t brown properly.
