These are the best sliders.
Sliders are such a great choice for a game day feast because they can be made in various stages ahead of time, if desired.
I’ll give suggestions on how you can do this below. And who doesn’t love a meal that doesn’t require utensils? Only a couple of hands and a mean appetite are needed!
But one thing I had never tried was The Blend. I’ll explain more why this new method pretty much changed the way I cook and how no burgers, tacos, meatloaf, lasagna, pasta sauce, or meatballs will ever be the same again.
Mushrooms and ground beef:
For this recipe, I decided to use two different kinds of mushrooms: white button and baby bella. No particular reason why other than I like a little variety, but you can take advantage of your favorite mushroom and use any variety you’d like.
Oh, how I’m counting the days until I can go foraging for chanterelles in the forest between my house and the coast. Be on the lookout for a new post with a mouthwatering Chanterelle Burger this fall!
What is The Blend, you’re wondering? Well allow me to share!
The Blend is a simple blending strategy that plays on mushrooms’ compatibility with meat in terms of taste and texture. Using an equal amount of mushrooms to your protein, all you have to do is:
- Chop up your favorite mushroom variety to match the consistency of the ground meat. I highly recommend roasting or sautéing the mushrooms for 10-15 minutes to enhance flavor. Then you allow them to fully cool before moving onto the next step;
- Blend the chopped mushrooms with the ground meat (beef, pork, chicken, turkey, or tofu);
- Cook your mushroom-meat blend to complete the recipe.
How to make the best sliders:
- You can most definitely use your hands to shape these meatball slider patties, however I happened to have a burger press with a slider insert. Not only did it create perfectly shaped and sized slider patties, but I couldn’t believe the mixture yielded a perfect dozen!
- I can tell you that had I not added the mushrooms, not only would the final meatball slider patty not have tasted as good, but I definitely wouldn’t have been able to create 12 patties from just one pound of ground beef.
- Don’t they look incredible? You can easily cook these mushroom meatball slider patties on the grill, but I chose to cook them in the oven. Either way, I’m confident they’ll turn out perfect.
Don’t they look amazing with all of that ooey gooey cheesy goodness?
Cooking with mushrooms:
I adore mushrooms year round in everything from savory breakfasts like omelets and scrambles to dinners like your traditional Salisbury Steak and Stroganoff.
I even use this 50/50 method of half ground beef and half ground mushrooms when I make tacos! The kids can’t tell and the flavor and texture is 100% better than straight ground beef.
You can incorporate mushrooms into any meal to simply add flavor, vitamins, and texture. You can get all sorts of information and ideas from The Mushroom Council’s website.
Fun fact: even though my husband and I are a huge lover of mushrooms, our kids are not. I can’t blame them only because I was the same way when I was little. But since mushrooms are such a great thing to incorporate into your diet, I want them to eat them.
Health benefits of mushrooms:
Mushrooms are low in calories, fat-free, cholesterol-free, gluten-free, and very low in sodium, yet they provide important nutrients, including selenium, potassium (8%), riboflavin, niacin, vitamin D and more.
Living in the Pacific Northwest, vitamin D is something we always need.
My son had no idea that the slider patties were 50/50 mushrooms and meat and I only let him in on my little secret after he devoured what I put in front of him.
So, rest assured that even if your kids or spouse don’t love mushrooms as much as you do, you may easily be able to incorporate them into a meal using this method.
What kind of bun is best for sliders?
One of the many tricks to make these mushroom meatball sliders absolutely perfect is to toast the buns. I’m not kidding when I say that I love Martin’s Potato Rolls so much that I have to fight the urge (and my kids) to avoid just shoving them straight out of the bag into our mouths.
Martin’s not only has the best taste, but they are so pillowy soft. That is why toasting is a must before you assemble the sliders.
Since you soak the patties in warm marinara sauce before assembling, your potato rolls would get mushy if you don’t take the time to toast them. But after only five minutes in the already hot oven, your golden brown perfection works as the perfect vessel to hold your mushroom meatball slider and transport it from the plate to your mouth!
And just look at those rolls! YUM!!!
Sliders with a kick!
I had some mini peppers in my refrigerator so I decided to toss them in a bit of olive oil and roast them in the oven while the slider patties were cooking.
This is optional and you can just as easily use jarred peppers, but I highly recommend it! Not only do they add to the taste, but they add a little pop of color which always makes me happy. My only regret is that I didn’t make more.
Cooking Tips!
If you’re planning on enjoying these mushroom meatball sliders at your next tailgating event, here are some ways you can plan ahead to make your outdoor prep a little easier:
- You can chop up the mushrooms and onions, saute them, and allow them to cool. Then combine them with the other patty ingredients and store them in a tupperware and take the blend with you.
- You can shape the patties and freeze them individually on a baking sheet covered in parchment paper. Once frozen through, store them in a resealable freezer bag. Prior to cooking, you can allow them to fully thaw or even put them on the grill or in the oven frozen. If frozen, they’ll just take longer to cook, but they’re small enough that it won’t matter.
- You can cook the patties ahead of time, combine with the marinara sauce, and simmer in a pot before assembling. Super easy!
- If you’re tailgating and only have a grill set up, the assembled sliders will heat through and melt perfectly if using a baking sheet.

Mushroom Blend Meatball Sliders
Ingredients
- 16 ounces mushrooms
- 1 medium sized red onion
- 1/4 cup olive oil
- 2 cloves garlic
- 1/4 teaspoon red pepper flakes
- 1 pound ground beef
- 1 cup bread crumbs
- 1/2 parmesan grated
- 1 large egg
- 1/2 cup fresh basil minced
- 28 ounces marinara sauce
- 12 ounces Italian cheese blend
- Martin's Party Potato Rolls
- roasted peppers optional
Instructions
- Combine the mushrooms and onion in a food processor and pulse until they are finely chopped and resemble the texture of ground beef.
- Heat the olive oil in the largest saute pan you have over high heat. Once the oil is hot, add the mushroom and onion mixture and allow to cook, stirring occasionally for 10-15 minutes. During the last minute of cooking, add garlic and red pepper, stir to combine, and allow to start turning golden brown and fragrant. Remove mixture from heat and allow to fully cool before combining with other ingredients.
- Preheat oven to 400 degrees F. In large bowl, combine ground beef, bread crumbs, grated parmesan, egg, fresh basil, and cooled mushroom mixture. Use hands to thoroughly mix but try not to over work the meat. Shape into 12 evenly sized slider patties.
- Bake in preheated oven for 20-25 minutes.
- Add marinara sauce to small pan and heat over low heat until heated through.
- Split Martin's Potato Rolls and toast in hot oven, open side up, for five minutes.
- To assemble sliders, dip each slider patty in the hot marinara sauce and place on top of toasted Martin's Potato Roll bottom. Cover with Italian cheese blend. Add roasted peppers, if desired. Return to oven for another 5-10 minutes to allow the cheese to fully melt.
- Serve with remaining warm marinara sauce. Enjoy!
