French Onion Ground Beef Skillet – Cheesy One-Pan Dinner

Chef Emma here, and this recipe was born on one of those evenings when I was craving all the rich, savory flavors of French onion soup but needed something more substantial and family-friendly for dinner. I had ground beef thawing on the counter, onions in the pantry, and a block of Gruyère cheese in the fridge.

That’s when inspiration struck—what if I could capture that iconic caramelized onion and melted cheese magic in a hearty, one-pan skillet dinner that my whole family would devour?

Thirty minutes later, I pulled that skillet off the stove—golden caramelized onions, perfectly seasoned ground beef, and a gorgeous blanket of melted, bubbly cheese on top. The aroma alone had my family circling the kitchen like hungry hawks.

That first bite was pure comfort food heaven—the sweet, deeply caramelized onions, the savory beef, the nutty melted cheese, all coming together in perfect harmony. My husband declared it “restaurant-quality,” and my kids asked if we could have it again the next night.

This French onion ground beef skillet has become one of our most-requested weeknight dinners. It’s everything you love about French onion soup—those sweet, jammy caramelized onions, rich beef broth flavors, and that irresistible melted cheese—but transformed into a hearty, satisfying meal that comes together in one pan.

½ teaspoon black pepper
1 teaspoon dried thyme (or 1 tablespoon fresh)
½ teaspoon dried oregano
2 tablespoons all-purpose flour (optional, for thickening)
1 cup beef broth
2 tablespoons Worcestershire sauce
1 teaspoon Dijon mustard (optional, adds depth)
1 bay leaf

For the Cheese Topping:

1½ cups shredded Gruyère cheese (or Swiss cheese)

Directions for French Onion Ground Beef Skillet

Step 1: Caramelize the Onions

Heat the butter in a large skillet over medium heat. Once melted and foaming, add the thinly sliced onions and a pinch of salt (about ¼ teaspoon). Cook, stirring frequently, for 15-20 minutes until the onions are deeply golden brown and caramelized. Don’t rush this step—the sweet, rich flavor of caramelized onions is what makes this dish special! If the onions start to stick or burn, reduce heat slightly and add a tablespoon of water to deglaze.

Step 2: Remove Onions and Brown the Beef

Once onions are beautifully caramelized, transfer them to a plate and set aside. In the same skillet (don’t clean it—all that fond adds flavor!), add the ground beef. Break it up with your spoon and cook over medium-high heat for 6-8 minutes until browned and no longer pink. Season with remaining salt, black pepper, thyme, and oregano. Drain any excess fat if needed, but leave about 1 tablespoon for flavor.

Step 3: Add Garlic and Flour

Add the minced garlic to the beef and cook for 30 seconds until fragrant. If using flour for a thicker sauce, sprinkle it over the beef and stir constantly for 1 minute to cook out the raw flour taste. This step creates a roux that will help thicken your sauce beautifully.

Step 4: Build the Sauce

Pour in the beef broth, Worcestershire sauce, and Dijon mustard if using. Stir vigorously to scrape up all those delicious browned bits from the bottom of the pan (that’s where the flavor is!). Add the bay leaf. Bring the mixture to a simmer and let it cook for 5-7 minutes until the sauce thickens slightly and reduces by about a third.

Step 5: Return the Onions

Add the caramelized onions back to the skillet, stirring them into the beef and sauce mixture. Remove the bay leaf. Taste and adjust seasoning—add more salt, pepper, or Worcestershire if needed. The mixture should be rich, savory, and slightly sweet from the onions.

Step 6: Add the Cheese

Reduce heat to low. Sprinkle the shredded Gruyère and mozzarella evenly over the top of the beef and onion mixture. Cover the skillet with a lid or tent loosely with aluminum foil. Let it sit for 3-5 minutes until the cheese is melted and bubbly.

Step 7: Optional Broiler Finish

For an extra-golden, bubbly cheese top (if your skillet is oven-safe), place the uncovered skillet under the broiler for 2-3 minutes, watching carefully to prevent burning. The cheese should be golden brown with some darker spots—just like French onion soup!

Step 8: Garnish and Serve

Remove from heat and let rest for 2-3 minutes. Garnish with fresh thyme sprigs or chopped parsley if desired. Serve hot over egg noodles, rice, mashed potatoes, or with crusty bread for soaking up all that delicious sauce!

Tips and Variations

Chef Emma’s Pro Tips:

Don’t rush the onions: The 15-20 minutes of caramelization is crucial for deep flavor
Use good beef broth: Quality broth makes a huge difference—low-sodium is best so you control salt
Grate your own cheese: Pre-shredded cheese doesn’t melt as smoothly due to anti-caking agents
Oven-safe skillet: Cast iron works perfectly and can go from stovetop to broiler
Save time: Caramelize onions ahead of time and store in the fridge for up to 3 days
Add mushrooms: Sauté sliced mushrooms with the onions for extra umami
Make it saucier: Add an extra ½ cup beef broth if you like more liquid

Delicious Variations:

French Onion Beef and Noodles: Stir in cooked egg noodles before adding cheese
French Onion Beef and Rice: Serve over white or brown rice
Loaded Version: Add sautéed mushrooms and a splash of red wine
Lighter Option: Use 93/7 lean ground beef and reduce cheese by half
Italian Twist: Use Italian seasoning and add diced tomatoes
Turkey Version: Substitute ground turkey for beef (add extra butter for moisture)
Stroganoff Style: Stir in ½ cup sour cream before adding cheese
Low-Carb/Keto: Serve over cauliflower rice or zucchini noodles
Make it a Soup: Double the broth and serve in bowls with crusty bread on top

Serving Suggestions:

Buttered egg noodles or pasta
Creamy mashed potatoes
Fluffy white or brown rice
Garlic bread or crusty French baguette
Simple side salad with balsamic vinaigrette
Roasted green beans or asparagus
Steamed broccoli or Brussels sprouts

Storage and Reheating:

Refrigerator: Store in an airtight container for up to 4 days
Freezer: Freeze before adding cheese for up to 3 months (add cheese when reheating)
Reheating: Reheat in a skillet over medium-low heat with a splash of broth, or microwave in 1-minute intervals
Meal Prep: Portion into containers with rice or noodles for easy lunches
Best Fresh: The cheese is crispiest and meltiest when freshly made

The ground beef provides complete protein with all essential amino acids, plus important nutrients like iron for healthy blood cells, zinc for immune function, and B vitamins (especially B12) that support energy metabolism and nervous system health.

The caramelized onions contribute fiber, potassium for blood pressure regulation, and beneficial compounds including quercetin, a powerful antioxidant with anti-inflammatory properties. The Gruyère and Swiss cheese provide calcium for strong bones and teeth, plus additional protein and vitamin A. The beef broth adds flavor while keeping sodium moderate when using low-sodium varieties.

Boost fiber: Serve over brown rice, quinoa, or whole wheat pasta instead of white rice
Add greens: Serve alongside or over a bed of arugula or mixed greens
Portion awareness: Pair with plenty of non-starchy vegetables to create a balanced plate

FAQs

Can I use ground turkey or chicken instead of beef?
Yes! Ground turkey or chicken work well, though they’re leaner so you may want to add an extra tablespoon of butter to prevent dryness. The flavor will be milder, so consider adding extra seasonings or Worcestershire sauce to boost the savory depth.

What’s the best type of onion to use?
Yellow onions are traditional for caramelizing because they develop the best sweet, rich flavor. Sweet onions (like Vidalia) also work beautifully. Avoid red onions as they can turn an odd color when caramelized for this long.

Can I substitute the Gruyère cheese?
Absolutely! Swiss cheese is the closest substitute and very traditional for French onion flavor. Other good options include fontina, provolone, or even sharp cheddar. Mozzarella alone is too mild, but mixing it with a sharper cheese works well.

How do I know when onions are properly caramelized?
Properly caramelized onions should be deeply golden brown (almost mahogany colored), very soft and jammy, and smell sweet and rich—not bitter or burned. This typically takes 15-20 minutes of patient stirring. If they start to stick, reduce heat and add a splash of water.

Can I make this in advance?
You can cook everything through step 5, then cool and refrigerate for up to 2 days. When ready to serve, reheat in the skillet, add the cheese, and proceed with melting. The caramelized onions can also be made days ahead.

Is this recipe gluten-free?
Yes, if you omit the flour thickener (the sauce will just be slightly thinner) and ensure your Worcestershire sauce is gluten-free (some brands contain malt vinegar). Use gluten-free sides like rice or potatoes instead of pasta.

Can I double the recipe?
Yes, but you’ll need a very large skillet (14-inch) or work in two batches. Alternatively, transfer everything to a large baking dish, top with cheese, and bake at 375°F for 15-20 minutes until bubbly.
