2 tablespoons beef base (such as Better than Boullion), divided
1 tablespoon Worcestershire sauce, divided
Kosher salt and black pepper, to taste
24 slider buns
12-16 ounces gruyere or swiss cheese, shredded
2 tablespoons sesame seeds
1 tablespoon fresh thyme
1 teaspoon onion powder
1 teaspoon garlic powder
Steps
Melt 2 tablespoons of the butter in a skillet over medium heat. Add in the onions and reduce the heat to medium low. Cook, stirring occasionally, until lightly caramelized, about 25-30 minutes. If the onions start to look dry or burnt, add a tablespoon of water to the pan.
In a large bowl, mix the ground beef with half of the beef base and half of the Worcestershire sauce. Season with salt and pepper.
Add the beef to the skillet full of onions. Increase heat to medium-high and brown the beef, breaking it up and mixing with the onions as you go. Once browned, drain off excess grease.
Preheat the oven to 350°F. Lightly grease a large baking sheet. Separate the tops from the bottoms of the slider buns. Fit the slider bottom buns tightly on the baking sheet.
Evenly distribute the beef and onion mixture over the bottom buns. Top with the gruyere cheese. Cover with the top buns.
In a microwave safe bowl, melt the butter with the remaining beef base. Stir in the remaining Worcestershire sauce and continue to mix until well-combined. Using a pastry brush, brush the beefy butter mixture over the top buns. Sprinkle with the sesame seeds, thyme, onion powder, and garlic powder.
Bake the sliders until the cheese is fully melted and the tops of the rolls are lightly browned, about 20 minutes.

Brenda Ingram on 2017-10-29 (5 stars): Made these last night for a Halloween party... followed everything to a T but I made my own rolls. They were fantastic!!! Rave reviews and nothing left of the sheet. Will make these again and again... Thanks for such a yummy recipe.
Cheryl Eames on 2018-10-21 (5 stars): This recipe is a hit everytime I make it. It never fails to please kids and adults alike, and I had become my go to recipe for any kind of gathering. For the kids who think they don't like onion, I puree the carmelized onions on my food processor and add them to the browned ground beef before loading up the sliders.
I have had to use dried thyme in a pinch, but the fresh thyme is so much prettier and tastes so much better.
Great recipe! It goes great with potato soup and a salad in winter or salad with chips in summer.
Alexa Corrales on 2018-12-04 (5 stars): I'm a fan of onions so I love doubling the onions since they shrink significantly when cooking. Tastes amazing on sweet Hawaiian rolls and topped with Trader Joe's Everything Seasoning!
I've made this 3 times and it's been a huge hit at every party. I even witnessed people secretly wrapping some up to take home later. Last time I doubled this recipe, and I kid you not, every slider was gone after 15 minutes of setting them out. Thanks for an awesome recipe!
Ahmed on 2019-02-05 (5 stars): I’ve made this recipe time and time again. It absolutely never disappoints! So easy and so delicious! Thank you so much!!
Jennifer on 2019-02-13 (5 stars): Made these with thinly sliced beef tenderloin I had left over in freezer. Our new favorite! Delicious. Thank you.
Kim Bullard on 2019-02-23 (3 stars): Tasted good but waaaaay too salty!
Jamie on 2019-04-07 (5 stars): This is an absolutely delish treat to make for friends, fam, etc. The prep work is a little tedious, but worth it!
Candace on 2019-07-30 (5 stars): Absolutely fantastic just the way it is!!!!
Laura on 2019-12-09 (4 stars): Thank you, these were an absolute winner at my daughter's party over the weekend!
Delaine Bradley on 2019-12-30 (5 stars): These were absolutely delicious!! I FOLLOWED your recipe to the T except I did use low sodium Better Then Bouillon. They were not too salty !Thank you for sharing your recipe.
Kris on 2020-02-01 (5 stars): Made these for New Years and they were requested for Super Bowl. Very good!
Dee Dee Poole on 2020-06-15 (5 stars): Delish, Delish, Delish!
Mary Ellen on 2021-02-16 (5 stars): These were great! We made them as directed, but shredded the gruyere. I think they’d be just as tasty with Swiss cheese, and more affordable for larger batches. I’ll definitely make these again and again! You can lower the sodium by choosing lower-sodium beef base and unsalted butter.
Kate on 2021-03-21 (5 stars): These are LIFE CHANGING!!! Obsessed and make them all the time. Thanks for helping me get out of my recipe rut. you rock!
Lisa on 2022-09-23 (5 stars): This is a recipe for life! Perfect in every way. Thanks for sharing
Marie on 2022-10-31 (5 stars): I made these for a tailgate (doubled the recipe to make 48). Since I cut them and wrapped them individually in foil, I didn't brush anything on top, but I did add fresh thyme on top of the cheese. They were a huge hit! Great recipe!
Lauren on 2023-07-04 (5 stars): These sliders are perfect. Super flavorful and juicy. I use 85/15 ground turkey. I’ve cooked them in the oven as per the recipe, but in the summer, I cook them in a skillet. You cant tell they’re not beef. 10/10 recommend.
Sarah Allen on 2023-12-03 (4 stars): I used this recipe as a base. The beef wasn't very flavorful and I found I needed to add salt. I did use the low sodium better than bouillon and salted butter. I added beef stock,sherry and about 2 tbsp sugar to the beef/onion mix and maybe a tsp of ground mustard. U also added some onion and garlic powders to the beef, a little more worcetershire and simmered about 15 minutes tasting along the way. I buttered and toasted the bottom buns with a little sprinkled parmesan before building the sliders.
Jocelyn on 2025-09-07 (5 stars): Kids and barbecue absolutely loved these. Easier instructions: cook up the ground beef in a skillet, add the Worcestershire and seasonings, great the onion into them so the kids don’t know what’s in it. Absolute hit. The leftovers are great when reheated in the air fryer for about 4 to 5 minutes. Melting the butter in a pan separately to top. The buns is always easier than the microwave for me. Delicious!
