Ingredients You’ll Need
Here’s your shopping list, friends. Keep it simple:
- 1 lb (450g) ground beef – Go for 80/20 for juicy sliders. Lean beef? Sure, but be prepared for “meh.”
- 1 large onion – The star of the show. Slice thin.
- 1 tbsp olive oil – For caramelizing those onions.
- 1 tbsp butter – Optional, but it takes your onions from “meh” to “OMG.”
- Salt & pepper – Basic but essential. Season like you mean it.
- 1 tsp garlic powder – Because garlic is life.
- Slider buns – Tiny bread happiness.
- Cheese slices – Optional, but who are we kidding? Cheese is required.
- Optional toppings – Lettuce, tomato, pickles, mustard, ketchup… you do you.
Pro tip: Don’t skip the caramelization. You can try, but your taste buds will silently judge you.
Step-by-Step Instructions
1. Caramelize Those Onions
Heat olive oil (and butter if you’re fancy) in a pan over medium-low heat. Toss in your sliced onions and a pinch of salt. Stir every few minutes and watch them slowly turn golden brown and sweet. This is the “patience pays off” moment. Takes ~20 mins.
2. Form the Sliders
Divide your ground beef into 8–10 small patties. Press them gently—don’t smash like you’re making hamburger roadkill. Sprinkle salt, pepper, and garlic powder.
3. Cook the Beef
Heat a skillet over medium-high. Cook sliders 2–3 minutes per side for medium, or longer if you like them well-done. No flipping a million times. Just one flip, promise.
4. Melt the Cheese
If you’re cheesing it up, place a slice on each patty a minute before removing from the skillet. Cover for a sec to get that melty goodness.
5. Toast the Buns
Slap those buns on the skillet, cut-side down, until slightly golden. This step is optional but trust me, it’s a game-changer.
6. Assemble Like a Pro
Bun bottom → patty → caramelized onions → optional toppings → bun top. Admire your work for a solid 3 seconds.
7. Devour
Serve hot. Maybe grab a napkin… or two. These little buggers are juicy.
Common Mistakes to Avoid
- Rushing the onions – Brown them slowly or suffer the bland life.
- Over-flattening the patties – You want juicy, not sad pancakes.
- Skipping seasoning – Ground beef without salt = flavorless sadness.
- Crowding the pan – Patties need space to sear. Don’t suffocate them.
- Eating cold sliders – Life’s too short. Warm sliders only.
Alternatives & Substitutions

- Beef alternatives: Turkey, chicken, or plant-based patties. Honestly, beef reigns supreme, but you do you.
- Cheese swaps: Cheddar, Swiss, provolone, or that fancy blue cheese if you’re feeling bougie.
- Bun options: Mini brioche, Hawaiian rolls, or even lettuce wraps if carbs are a concern.
- Onion hacks: Pre-sliced frozen onions work in a pinch, but fresh wins every time.
- Spice it up: Add smoked paprika, chili flakes, or a dab of hot sauce. Your tongue will thank you.
