Fire up the grill for a hand-held, soup-inspired, fantastic grilled supper: Â Stuffed French Onion Soup Sliders!
Think savory French Onion Soup – beefy broth, sweet caramelized onions, melted cheese, and toasted bread – in slider form. I want to pinch their baby burger cheeks!
I don’t know how or why I came to crave these stuffed burgers (gosh I’m interesting) but I do know that we’re on day 2 of “sticky floor”, aka hot & humid, weather around here, and nothing sounds better than a quick dinner made primarily on the grill. These are soooooo good, and really easy too!
Start the sliders by caramelizing a couple jumbo sweet onions, which are arguably the star of both French Onion Soup AND these sliders. Just peel the onions, cut them in half, then thinly slice each half.
Next, melt 1 Tablespoon each butter and extra virgin olive oil in a large skillet over medium heat. Like a 5 out of 10. You want these babies to cook looow and slooow.
Add the onions, toss to coat in the butter and oil, then let them cook, stirring every so often, for 20-30 minutes.
Slowly the onions start to transform and sweeten up.
The natural sugars in the onion will caramelize, and soon you’ll have a skillet full of what I fondly refer to as, onion candy.
Seriously, you won’t believe how sweet these suckers get!
Mmkay. While the onions are caramelizing, get to work on the slider portion of the program. You’ll need 1lb lean ground beef (I used 90/10) and 2 Tablespoons Onion Soup & Dip Mix (that’s half of 1 packet.)
The flavor from the beef mimics the savory broth of French Onion Soup, while the onion soup & dip mix contains a perfect blend of yummy, soup spices.
Add in 1/4 cup water, then mix it all up with your hands.
Form the mixture into 8, equal sized balls. I usually divide the beef into quarters in the bowl, then divide each quarter in half to make sure everyone comes out the same size.
Next, turn your attention to da cheese. Fontina! My favorite cheese, due to its mild taste, creamy texture, and tremendous melting abilities.
Fontina is typically sliced then broiled over bowls of French Onion Soup, but today we’re gonna use it to stuff inside the sliders.
Cut the cheese into 8 cubes, then press your thumb into the middle of each beef ball and stuff a cube inside. Seal the beef tightly around the cheese so it doesn’t leak out while the sliders are grilling. Press the balls into patties, then head out to the grill.
Preheat the grill to medium-high heat, then grill the sliders for 5-6 minutes a side. Do not grill over high heat, as the cheese will burst out of the sliders and onto the grates. Wasted melted cheese is a terrible thing.
During the last minute or so, pop the slider rolls onto the grill to toast up. It’s my nod to French Onion Soup’s toasted bread hunk floating under the cheese and amongst the beefy broth. I used tea rolls, but any small bun will do.
When the sliders are cooked through, remove them to a plate, cover with foil, and let them rest for at least 5 minutes.
Place the rested sliders onto the toasted buns, top with caramelized onions, and dig in!
You could literally put caramelized onions on anything, and I would gobble it up. They are sticky-sweet, and insanely delish.
The molten flow of fontina stuffed in the center comes in a close second though, and I just love how the onion soup & dip mix makes these sliders taste just like their soupy sister.
Plus, MINI THINGS!
Have a good one!

These were amazing. I made them last night (it was my first attempt of grilling). My husband said they were one of the best burgers that he ever had! Thanks for the recipe! This one is a keeper!

I wish I would have carmelized 6 onions last night, so I could put them on everything I eat for the next two errr 1 days. My husband and I give these 4 thumbs up.

Made these for dinner and OH MY! These are SO YUMMMMMMY! The caramelized onions are like candy and are such a nice balance to the savory oniony flavor in the beef. I want to make a normal size burger of this next time…oh yes…there WILL be a next time! Kristin, once again, you’ve knocked it out of the park.
Wendy 05.09.2012
Can you make the caremelized onions the day before you make the burgers? I have a tight dinner timeframe tomorrow, so if I can do that part today, it will make life easier.
Iowa Girl Eats 05.09.2012
Definitely! You can make them a couple days in advance!
Gwen 05.09.2012
These look yum! I have put onion soup mix in burgers before and I have stuffed burgers with cheese, but never the two at the same time. Brilliant idea!

French Onion Soup is one thing I truly do miss since becoming vegan, and I don’t think there’s any way to veganize it without being like, What the HELL is this crap!?
Ashley @ Coffee Cake and Cardio 05.03.2012

Chelsea @ Chelsea Eats Treats 05.03.2012
These look amaaaaazing. I need to run out and buy fontina cheese and soup mix asap so I can make these!
Emilie @ Emilie's Enjoyables 05.03.2012
I looove caramelized onions but I don’t love french onion soup. But I love french onion mix, like in a dip. Weird? Either way, I definitely think I would love these burgers.

Looks great…I’m not sure if you care about MSG but I just discovered that Lipton’s Onion Soup/Dip Mix has MSG in it. I was using it for a meatloaf and decided to look at the ingredients. So beware if you want to avoid MSG :)
