How to Make French Onion and Beef Skillet Dinner with Potatoes and Brussels Sprouts Recipe
Step 1: Prepare the Steak
Start by cutting your boneless sirloin steak into thin, even strips. This helps the beef cook quickly and absorb all the wonderful flavors from the skillet. Season the strips generously with salt and pepper to enhance the natural beef flavor.
Step 2: Caramelize the Onions
In a large skillet, melt the butter over medium heat. Add the thinly sliced sweet onions and cook, stirring occasionally, until they soften and become golden, about 10 minutes. Then stir in the balsamic vinegar and sugar. Keep cooking for another 5 to 10 minutes until the onions are deeply caramelized, fragrant, and full of sweet, tangy goodness.
Step 3: Sear the Steak
Push the onions to one side of the skillet to make room. Add the seasoned steak strips to the empty space and cook for 3 to 5 minutes, turning occasionally, until the beef is nicely browned on all sides. This step locks in that savory flavor you crave.
Step 4: Simmer with Vegetables
Pour the beef broth evenly over the steak and onions, then add the thinly sliced red potatoes and quartered Brussels sprouts. Gently stir everything together, cover the skillet, and let it simmer for 10 to 15 minutes. This gentle cook breaks down the vegetables just enough to be tender but still pleasantly textured.
Step 5: Melt the Cheese and Serve
Once the veggies are perfectly cooked, sprinkle the shredded Gruyère cheese on top. Cover the skillet again and allow the cheese to melt for about a minute. The result is a gooey, golden blanket of cheesy goodness that brings the entire dish to the next level. Serve while it’s warm and enjoy the magic!
How to Serve French Onion and Beef Skillet Dinner with Potatoes and Brussels Sprouts Recipe
Garnishes
A sprinkle of freshly chopped parsley or chives adds a pop of color and a fresh herbal lift that beautifully contrasts the rich, savory flavors of this dish. For a little extra indulgence, a dollop of sour cream can also bring creaminess and tang that play nicely with the melted Gruyère.
Side Dishes
This dish is wonderfully filling on its own, but if you want to add a side, a crisp green salad with a light vinaigrette or some crusty artisan bread works perfectly. The bread is especially great for soaking up any leftover juices in the skillet.
Creative Ways to Present
For an elegant family-style presentation, serve this skillet straight from the pan at the center of the table so everyone can dig in. Alternatively, spoon the mixture onto warm plates and add a fresh herb garnish on top for a restaurant-worthy finish that feels both special and inviting.
Make Ahead and Storage
Storing Leftovers
Leftover French Onion and Beef Skillet Dinner with Potatoes and Brussels Sprouts Recipe keeps well in an airtight container in the refrigerator for up to 3 days. Make sure it cools down completely before storing to maintain the best texture and flavor.
Freezing
This dish can be frozen if you want to save it for another time. Place cooled portions in freezer-safe containers or heavy-duty freezer bags, removing as much air as possible. It will keep well for up to 2 months without losing its delicious taste.
Reheating
To reheat, thaw frozen portions overnight in the fridge if possible. Warm it gently in a skillet over medium-low heat until heated through, adding a splash of beef broth if it starts to dry out. You can also reheat in the microwave, but stirring occasionally helps keep even warmth and prevents sogginess.
FAQs
Can I use a different cut of beef for this recipe?
Absolutely! While sirloin is great for tenderness and flavor, you can use ribeye, flank steak, or even chuck steak cut thinly. Just adjust cooking times if needed to ensure the beef stays tender.
Are there substitutions for Gruyère cheese?
Yes! If Gruyère isn’t available, Swiss cheese or even mozzarella can work, though Gruyère provides that classic nutty, creamy flavor that perfectly complements this dish.
Can I make this recipe vegetarian?
Definitely! Skip the beef and replace the beef broth with a rich vegetable broth. You can add mushrooms or plant-based protein for a similar hearty texture.
Is it possible to use frozen Brussels sprouts or potatoes?
Frozen vegetables can be a convenient substitute, but fresh is best for this recipe since the short cooking time helps preserve texture. If using frozen, thaw and drain them well first to avoid excess moisture.
What wine pairs well with French Onion and Beef Skillet Dinner with Potatoes and Brussels Sprouts Recipe?
A medium-bodied red wine like Merlot or Pinot Noir pairs beautifully, complementing the beef and caramelized onions without overpowering their flavors.
