Ingredients for Grilled Steak with Sautéed Onions and Cheesy Broccoli
This recipe uses simple, high-quality ingredients to create a meal that’s both approachable and impressive. Here’s what you’ll need to bring this dish to life:
For the Grilled Steak (Serves 2):
- 2 bone-in ribeye steaks (about 1–1.5 inches thick; substitute with sirloin, New York strip, or filet mignon if preferred)
- 1 tbsp olive oil (for brushing; avocado oil works for higher heat)
- 1 tsp garlic powder (for savory depth)
- 1 tsp onion powder (for a subtle, umami kick)
- 1 tsp freshly ground black pepper (adjust to taste)
- Kosher salt to taste (about 1 tsp per steak, depending on size)
- 1 tbsp fresh rosemary, finely chopped (optional, for an aromatic, earthy note)
- Optional: 1 tsp smoked paprika (for a smoky flavor boost)
For the Sautéed Onions:
- 2 medium red onions, thinly sliced (yellow or sweet onions work too)
- 1 tbsp olive oil (or butter for richer flavor)
- 1 tsp balsamic vinegar (optional, for a touch of sweetness and tang)
- Kosher salt and freshly ground black pepper to taste
- Optional: 1 tsp fresh thyme (for an herbaceous twist)
For the Cheesy Broccoli:
- 2 cups broccoli florets (fresh or frozen; fresh offers better texture)
- ½ cup shredded cheddar cheese (sharp cheddar for bold flavor; substitute with mozzarella or a blend)
- ¼ cup milk or heavy cream (heavy cream for a richer sauce; milk for a lighter option)
- Kosher salt and freshly ground black pepper to taste
- Optional: Pinch of garlic powder or red pepper flakes (for extra flavor)
Equipment:
- Grill (gas, charcoal, or indoor grill pan)
- Meat thermometer (optional, for precise doneness)
- Skillet or sauté pan
- Saucepan or steamer for broccoli
- Tongs, spatula, and aluminum foil (for resting steaks)
Step-by-Step Instructions for a Flavorful Feast
This meal comes together in about 40–45 minutes, with the components prepared simultaneously for efficiency. Here’s how to make it:
Step 1: Prepare the Steaks
- Season the steaks: Pat the ribeye steaks dry with paper towels to ensure a good sear. Brush both sides with 1 tbsp olive oil, then evenly sprinkle with garlic powder, onion powder, black pepper, and kosher salt. If using, add the chopped rosemary or smoked paprika for extra flavor. Gently press the seasonings into the meat.
- Let the steaks sit at room temperature for 15–20 minutes. This ensures even cooking and prevents the steaks from seizing up on the hot grill.
Step 2: Grill the Steaks
- Preheat the grill to medium-high heat (about 400–450°F / 204–232°C). If using a charcoal grill, ensure the coals are glowing and covered with ash. For a grill pan, heat over medium-high until very hot.
- Place the steaks on the grill and cook for 4–5 minutes per side for medium-rare (internal temperature of 130°F / 54°C). Adjust cooking time for your preferred doneness: 3–4 minutes per side for rare (125°F / 52°C), 5–6 minutes for medium (135°F / 57°C), or 6–8 minutes for medium-well (140°F / 60°C).
- Remove the steaks from the grill and tent loosely with aluminum foil. Let them rest for 5 minutes to redistribute the juices, ensuring a tender, juicy bite.
Step 3: Sauté the Onions
- While the steaks grill, heat 1 tbsp olive oil in a skillet over medium heat. Add the sliced red onions and cook, stirring occasionally, for 10–12 minutes until soft, golden, and slightly caramelized.
- If using, drizzle in the balsamic vinegar and stir for another 1–2 minutes to enhance sweetness. Season with salt, pepper, and optional fresh thyme. Set aside, keeping warm.
Step 4: Prepare the Cheesy Broccoli
- If using fresh broccoli, steam or boil the florets in a saucepan for 5–7 minutes until tender but still vibrant green. If using frozen, follow package instructions for steaming or microwaving. Drain any excess water.
- Return the broccoli to the saucepan over low heat. Add the milk or heavy cream, shredded cheddar cheese, salt, pepper, and optional garlic powder or red pepper flakes. Stir gently until the cheese melts and forms a creamy sauce, about 2–3 minutes.
- Keep warm until ready to serve, stirring occasionally to prevent sticking.
Step 5: Assemble and Serve
- Plate each grilled steak and spoon the sautéed onions over the top, letting their savory sweetness complement the meat.
- Serve with a generous portion of cheesy broccoli on the side, drizzling any extra cheese sauce over the florets for added decadence.
- For a gourmet touch, drizzle any collected steak juices over the broccoli or add a squeeze of fresh lemon juice to brighten the flavors.

Tips for Success
- Steak Selection: Bone-in ribeye adds rich flavor, but boneless cuts or other steaks like sirloin or T-bone work well. Choose cuts about 1–1.5 inches thick for best results.
- Grill Marks: For picture-perfect grill marks, avoid moving the steaks for the first few minutes of cooking. Rotate 45 degrees halfway through each side for a crosshatch pattern.
- Caramelized Onions: Cook onions low and slow for deeper caramelization if time allows (up to 20 minutes). Add a pinch of sugar to speed up the process.
- Cheesy Broccoli Hack: For a thicker sauce, mix in 1 tsp cornstarch with the milk before adding it to the broccoli. For extra creaminess, use half cream cheese, half cheddar.
- Make Ahead: Season the steaks and slice the onions up to a day in advance. Store in the fridge until ready to cook. Broccoli can be steamed ahead and reheated with the cheese sauce.
Serving Suggestions
This hearty meal is a complete dinner on its own but can be elevated with thoughtful pairings:
- Classic Comfort: Serve with mashed potatoes or roasted garlic potatoes to soak up the steak juices and complement the cheesy broccoli.
- Wine Pairing: A bold red wine like Cabernet Sauvignon or Malbec pairs beautifully with the steak’s richness. For a non-alcoholic option, try a sparkling apple cider.
- Light Side: Add a crisp green salad with vinaigrette to balance the richness of the meal.
- Special Occasion: Garnish with fresh herbs like parsley or chives and serve with a warm dinner roll for an upscale touch.
