Ingredients
- 1 large yellow onion, thinly sliced
- 5 tablespoons of butter, divided
- ¼ teaspoon of granulated sugar
- 12 Hawaiian sweet roll slider buns
- ½ cup French onion dip
- 1 pound sliced roast beef
- 10 slices provolone cheese
- 2 cloves of garlic, minced
- 1 tablespoon parsley, finely chopped
- 1 cup beef broth
- ¼ cup red wine
- 1 tablespoon Worcestershire sauce
- 1 tablespoon soy sauce
Directions
First things first, preheat your oven to 350°F (175°C). This is always the first step I take to ensure everything cooks just right.
Next, grab a skillet and melt 3 tablespoons of butter over medium heat. Once it’s nice and hot, toss in your sliced onions and sprinkle them with the sugar. Remember to cover the skillet and let those onions cook until they turn a beautiful golden brown—this usually takes about 15-20 minutes, and don’t forget to stir occasionally to avoid burning!
While the onions are working their magic, take your Hawaiian slider buns and slice them in half lengthwise, keeping them attached at the back. Lay them out flat on a baking sheet lined with parchment paper and spread the French onion dip on the bottom halves.
Now, it’s time to layer! Start with the roast beef, then add the provolone cheese, followed by those delicious caramelized onions. Once you’ve piled it all up, place the top halves of the buns back on.
In a small bowl, melt the remaining butter and mix in the minced garlic and chopped parsley. Brush or drizzle this aromatic mix over the top of the buns for that extra flavor kick.
Pop the sliders in the oven and give them about 10-15 minutes or until the cheese is melty and bubbly. If you notice the buns browning too quickly, just lightly cover them with aluminum foil.
While the sliders are baking, mix all the ingredients for the au jus in a small saucepan. Simmer it over low heat for about 10 minutes for a rich dipping sauce.
Finally, serve your delicious sliders alongside the warm au jus for dipping, and watch your family enjoy every bite!
Storing Suggestion
Store any leftover sliders in an airtight container in the refrigerator for up to three days. When you’re ready to enjoy them again, just reheat in the oven for a few minutes, and they’ll taste almost as good as fresh!
Cooking Tips
If you find yourself short on time, you can use pre-packaged caramelized onions for a quick shortcut. Also, feel free to mix in diced mushrooms with the onions for extra depth or use fresh herbs to elevate the flavor further.
Serving Suggestions
These sliders are perfect as a standalone meal, but you can pair them with a simple mixed greens salad or crispy potato chips for added crunch. A chilled glass of iced tea or a light beer also complements this dish perfectly!
Ingredient Substitutions
If you can’t find Hawaiian rolls, regular slider buns or even mini baguettes can be a good alternative. You can also use cheddar cheese in place of provolone for a sharper taste.
Seasonal Variations
In the spring, consider adding sautéed asparagus or fresh herbs to the mix for a vibrant twist. During the fall, using caramelized apples alongside onions can add a sweet touch that perfectly complements the savory beef.
Allergen Information
This recipe contains dairy and gluten. To make it gluten-free, choose gluten-free buns and be cautious with sauces that may contain hidden gluten. For dairy issues, try using dairy-free cheese and butter alternatives.
FAQ
Can I make these sliders ahead of time?
Absolutely! You can assemble the sliders in advance and store them in the refrigerator until you are ready to bake. Just add a few extra minutes to the baking time if they are cold from the fridge.
What can I serve with these sliders?
These sliders pair nicely with a side of coleslaw or a simple vegetable platter. A warm bowl of soup is also a comforting option, especially on colder days.
Can I freeze the leftovers?
Yes, you can freeze leftover sliders! Just wrap them tightly in foil and store them in the freezer for up to a month. Thaw in the refrigerator before reheating in the oven.
Is there a vegetarian option for this dish?
You could easily substitute the roast beef with grilled veggies or a hearty portobello mushroom. Use a plant-based cheese to keep it vegetarian and enjoy the same delicious flavors!
How do I know when the onions are caramelized properly?
Caramelized onions should be soft, golden brown, and sweet. If they are still crunchy or a pale yellow, they need more time on the stove. Remember to stir frequently, especially towards the end!
Can I use a different type of cheese?
Of course! While provolone adds a nice creaminess, you can use mozzarella for a milder flavor or Swiss cheese for a nuttier taste. Each option will yield a deliciously cheesy slider!
