🧀 The Ingredients
Using leftover pot roast and gravy makes the ingredients for pot roast sliders simple, while the caramelized onions and melty Swiss cheese take them to the next level of flavor. Find ingredient notes (including substitutions and variations) below.
🍔 Substitutions and Variations
- Leftovers – Leftover pot roast is tender and delicious. However, this will also work perfectly with leftover brisket, grilled pork tenderloin, or even roast turkey. If you don’t have leftovers, pick up some roast beef from your local deli, heat it in a skillet on the stove, and layer for amazing sliders!
- Cheese – Swiss is wonderful. However, sliced Gruyere is heavenly, too. Sliced Gouda, white cheddar, or even mozzarella all make great substitutions. You really can’t go wrong! Even crumbled blue cheese is wonderful!
- Toppings – Caramelized onions take about 40 minutes to make, but they can be made up to 24 hours in advance (just reheat on the stove). Sautéed mushrooms can be substituted, or added to the sliders.
- Buns – Pick up sliders in the sliced bread section in most well-stocked supermarkets. You can also make full sandwiches of them on easy skillet dinner rolls, pretzel buns, or sliced white bread.

Expert Tip
If you don’t have leftover gravy, or you need to add to what you have, simply melt 2 tablespoons unsalted butter in a skillet and then stir in two tablespoons. Cook for 1 to 2 minutes, stirring frequently. Whisk in beef broth and stir until thickened to the desired consistency, usually about 3 to 5 minutes. Season to taste with salt and pepper.
