Simple Method

Making these meatballs is a very straightforward process that anyone can master. You will start by browning the beef to lock in all those juices. The secret is all in the slow-cooked onions that create the base.

Even if you are a beginner, you can handle this skillet meal. We use one pan to keep your cleanup quick and easy tonight. You just need a little patience while the onions turn golden and sweet.

Ingredients You’ll Need

Most of these items are likely already waiting in your kitchen right now. We use fresh, simple ingredients to build layers of incredible flavor.

• 1 lb ground beef (80/20 blend)
• 1/2 cup panko breadcrumbs
• 1 large egg, beaten
• 2 cloves garlic, minced
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper
• 3 large yellow onions, thinly sliced
• 3 tablespoons unsalted butter
• 1 tablespoon olive oil
• 2 tablespoons all-purpose flour
• 2 cups low-sodium beef broth
• 1 teaspoon Worcestershire sauce
• 1 teaspoon balsamic vinegar
• 1 tablespoon fresh thyme leaves
• 1.5 cups Gruyère cheese, shredded
• 2 tablespoons fresh parsley, chopped

Step-by-Step

1. Mix beef, panko, egg, garlic, salt, pepper, and half the thyme in a bowl.
2. Form the mixture into 1-inch meatballs using your hands or a small scoop.
3. Melt butter and oil in a large oven-safe skillet over medium heat.
4. Add sliced onions and cook for 40 minutes until they are deeply caramelized.
5. Remove onions and sear meatballs in the same pan until they are browned.
6. Put onions back in and stir in the flour for two minutes.
7. Slowly whisk in the broth, Worcestershire sauce, and balsamic vinegar.
8. Simmer meatballs in the sauce for 10 minutes until they are cooked through.
9. Top with Gruyère and broil for 3 minutes until the cheese is bubbly.
10. Garnish with remaining herbs and serve while hot.

Best Ways to Enjoy It

I highly recommend serving these meatballs over a pile of creamy mashed potatoes. The rich onion gravy is far too good to let any go to waste. You could also use crusty bread to soak up every last drop.

For a lighter option, a simple green salad provides a nice fresh crunch. Set the table, light a candle, and enjoy this perfect date night meal. It feels elegant but stays cozy enough for a casual family Tuesday.

Storage & Reheating

If you have leftovers, they will stay fresh in the fridge for three days. Store them in an airtight container to keep the meatballs tender and moist. This dish actually tastes even better the next day as flavors mingle.

To reheat, place them in a small baking dish in the oven. Heat at 350°F for about 15 minutes until the cheese melts again. You can also use a microwave for a quick and easy lunch.

Recipe Tips

• Don’t rush the onions because that deep brown color provides all the flavor.
• Use a cookie scoop to make sure all your meatballs are the same size.
• Wet your hands slightly to keep the meat from sticking while you roll.
• Swap Gruyère for Swiss cheese if you want a more affordable option today.
• For a holiday crowd, you can easily double this recipe in a larger pan.
• Make sure your skillet is oven-safe before you put it under the broiler.
• Add a splash of dry white wine to the onions for extra depth.

Ways to Switch It Up

• Try ground turkey instead of beef for a lighter version of this dish.
• Use gluten-free breadcrumbs to make this recipe safe for sensitive tummies.
• In the summer, swap the heavy gravy for a lighter beef au jus.
• Add a pinch of red pepper flakes if you enjoy a little heat.

Quick Answers

Can I make these ahead of time?

Yes, you can roll the meatballs a day early and keep them chilled. You can even caramelize the onions in advance to save time at dinner.

What if I don’t have an oven-safe skillet?

No problem at all! Just transfer everything to a baking dish before adding the cheese. Then you can safely broil it until golden.

Will my kids like the onions?

Caramelized onions are very sweet and mild compared to raw ones. Most kids love the sweet flavor and melty cheese on top.

I hope this cozy meal brings a little extra warmth to your home this week. There is nothing like a cheesy, home-cooked dinner to make everything feel better. Give it a try and enjoy every savory bite!
