Frozen cheeseburger sliders are small, cheesy burgers made with frozen beef patties, soft rolls, and simple toppings, baked together for an easy meal or party tray. Cooking the patties from frozen saves a thawing step, while baking the assembled sliders keeps the buns warm and the cheese nicely melted.
Ingredients
- 12 frozen, fully raw beef slider patties, about 2 ounces each (1½ pounds total), plain and unseasoned
- 12 slider rolls, kept connected if they come in a sheet
- 6 slices cheddar or American cheese, cut in half
- 1 tablespoon neutral oil, only if needed for your skillet or baking dish
- ½ teaspoon kosher salt, or to taste, if the patties are unseasoned
- ¼ teaspoon black pepper
- ½ small yellow onion, finely diced (about ⅓ cup)
- 2 tablespoons unsalted butter, melted
- 1 teaspoon sesame seeds, optional
- 12 dill pickle chips, optional
- Ketchup, mustard, or burger sauce, for serving
Instructions
- Heat the oven and prepare the rolls. Heat the oven to 375°F (190°C). Line a rimmed baking sheet with foil or parchment for easier cleanup. Slice the connected rolls horizontally through the middle, keeping the tops and bottoms intact as sheets. Set the top sheet aside. Arrange the bottom sheet on the prepared pan.
- Cook the patties from frozen. Heat a large skillet over medium heat. Add a little oil if the pan is not nonstick, then arrange the frozen patties in a single layer without crowding. Season the exposed sides with salt and pepper. Cook according to the package directions, turning as directed; small patties commonly take about 4–6 minutes per side, but thickness and brand affect the time. Cook in batches if necessary. Do not rely on color or time alone: the center of every patty must reach 160°F (71°C), checked with an instant-read thermometer. Transfer the cooked patties to a clean plate.
- Soften the onion. If you prefer tender onion rather than a raw crunch, add the diced onion to the skillet after the patties are cooked. Cook over medium heat for 3–5 minutes, stirring, until softened. If the pan is dry, add a teaspoon of water. You can skip this step and use the onion raw, or leave it off.
- Assemble the sliders. Set the cooked patties evenly over the roll bottoms. Add the softened onion, if using, then cover each patty with half a slice of cheese. Add a pickle chip to each slider if desired. Keep sauces off the buns for now if you want to minimize sogginess; serve them on the side.
- Top and butter. Place the sheet of roll tops over the sliders. Brush the tops evenly with melted butter and scatter on sesame seeds, if using. Cover the pan loosely with foil so the rolls heat through without browning too quickly.
- Bake until hot and melty. Bake for 10 minutes, then remove the foil and bake for another 3–5 minutes, until the cheese is melted and the tops are lightly golden. The oven step warms the assembled rolls; it does not replace cooking the raw patties to 160°F. If the sliders have cooled while you assembled them, check one in the center and bake a few minutes longer as needed.
- Separate and serve. Let the pan rest for about 2 minutes. Cut along the roll seams with a serrated knife, or slice between the patties, and serve hot with ketchup, mustard, or burger sauce.
Tips
- Check the package first. This method is for plain, fully raw frozen beef patties. If yours are precooked, follow their package directions and heat them to 165°F (74°C) for reheated leftovers or ready-to-eat frozen products as directed. Patties that are unusually thick may need more skillet time.
- Use a thermometer. Beef patties can brown before their centers are safe. Check each patty where practical, especially if they vary in size; ground beef should reach 160°F (71°C).
- Keep the buns soft. Cook patties separately before assembling. Putting raw frozen beef on the rolls can leave the buns soggy and makes it harder to cook the centers evenly.
- Adjust the cheese and seasoning. American cheese melts especially smoothly; cheddar gives a stronger flavor. If the patties are already seasoned, skip or reduce the added salt.
Serving Suggestions
Serve the sliders straight from the pan with crisp oven fries, potato wedges, coleslaw, or a green salad. A platter of pickles, sliced tomato, lettuce, and sliced onion lets everyone add fresh toppings at the table without making the warm buns soggy. Put ketchup, mustard, mayonnaise, and burger sauce in small bowls for dipping or spreading just before eating.
Variations
Swap cheddar for Swiss, pepper jack, or provolone, using about half a slice per slider so the cheese melts without overwhelming the small rolls. Add cooked bacon, sautéed mushrooms, or caramelized onions after the patties are cooked. For a tangy finish, brush the roll tops with a mixture of melted butter and a teaspoon of Worcestershire sauce. You can also use turkey or chicken slider patties, but follow the package directions and cook poultry to 165°F (74°C); do not use the beef temperature for poultry.
Storage and Reheating
These sliders are best served just after baking. Refrigerate leftovers within 2 hours of cooking (within 1 hour if the room or outdoor temperature is above 90°F/32°C). Store in an airtight container in the refrigerator for up to 3–4 days. For better texture, keep extra sauce and fresh toppings separate.
To reheat, place sliders in a baking dish, cover loosely with foil, and warm at 325°F (165°C) for about 10–15 minutes, until the centers reach 165°F (74°C). A microwave works for one or two sliders: heat in short 30-second bursts, checking that the center is hot, though the buns will be softer. Avoid leaving cooked sliders at room temperature for more than 2 hours, and reheat only the portions you plan to eat.
Frequently Asked Questions
Can I cook the frozen patties in the oven instead of a skillet?
Yes. Arrange them in a single layer on a rimmed baking sheet and bake at the temperature and time on the package, turning if directed. Check the center of each patty with a thermometer and continue cooking until it reaches 160°F (71°C). Then assemble the sliders and bake as directed to melt the cheese and warm the rolls.
Should I thaw the patties first?
No. For this recipe, cook the patties directly from frozen, following the package instructions. Thawing is unnecessary and can make the meat harder to handle. If you do thaw patties in the refrigerator, cook them promptly and do not thaw them on the counter.
Can I assemble these ahead of time?
For the best texture, cook the patties and assemble shortly before baking. You can dice the onion, slice the cheese, and separate the rolls in advance. Avoid assembling raw patties on the buns, and do not leave cooked meat unrefrigerated while preparing other food.
Can I use a different kind of roll?
Yes. Hawaiian rolls, potato rolls, or other soft dinner rolls work well if they are close to slider size. If the rolls are individual rather than connected, arrange them snugly in a baking dish and place one patty on each bottom half.
Can I freeze leftover cooked sliders?
Yes, though the buns may soften after thawing. Cool them promptly, wrap individually or pack airtight, and freeze for up to 2–3 months for best quality. Thaw in the refrigerator, then reheat covered in a 325°F (165°C) oven until the centers reach 165°F (74°C).
How do I keep the sliders from getting soggy?
Cook and drain the patties before assembling, and add wet condiments at the table. Use only a light coating of butter on the tops and avoid trapping excess steam after baking; uncover for the final few minutes so the rolls can lightly toast.
