Perfectly marinated beef, rolled up with gooey cheese, garlicky spinach, and herbs, sliced into dramatic spiralsthis is the kind of meal that makes people assume you own a meat thermometer and your life. (We’ll make the first part true today.)

What Is London Broil (Really)?

“London broil” is not a specific cut of beefit’s a cooking method and a menu name that sounds fancy enough to charge extra. In most U.S. supermarkets, London broil is usually:

• Top round roast or steak (lean, affordable, benefits from marinating)
• Sometimes flank steak (also lean, full of flavor, great for stuffing and slicing)

Because these cuts are lean, they shine when:

• Marinated for flavor and tenderness
• Cooked to medium-rare or medium (or at least to a safe 145°F with rest time, per USDA guidance for whole-muscle beef steaks)
• Sliced thinly across the grain

Stuffing and rolling the steak adds moisture, richness, and a show-stopping presentation while keeping the core idea of London broil: big flavor from a budget-friendly cut. Techniques and flavor combinations for stuffed flank/top-round rolls are widely used in American kitchens and trusted sources, combining marinades with leafy greens, cheeses, and aromatics to keep the meat juicy and impressive.

Key Flavor Strategy for Stuffed London Broil

1. Choose the Right Cut

Look for a 2–2.5 lb London broil labeled top round or flank steak:

• Even thickness (easier to butterfly and roll)
• Minimal sinew or silver skin
• Good length for spirals once sliced

2. Build a Bold Marinade

Classic, reliable flavor profiles from U.S. home-cooking staples use a balance of salt, acid, umami, aromatics, and a touch of sweetness:

• Soy sauce or Worcestershire sauce for umami
• Balsamic or red wine vinegar or lemon juice for brightness
• Olive oil for richness
• Garlic, onion, herbs (rosemary, thyme, parsley)
• A pinch of brown sugar or honey to balance and help browning

This style of marinade is consistent with many popular London broil recipes used by American cooks and food sites.

3. Smart Stuffing Combo

To keep things flavorful without turning your roll into a lava flow of cheese, we’re using:

• Baby spinach – adds color, moisture, and a “this is kind of healthy” vibe
• Melty cheese – provolone or mozzarella
• Sharp accent – Parmesan or feta for a salty, savory punch
• Aromatics – sautéed onion, garlic
• Optional extras – sun-dried tomatoes, roasted red peppers, or herbs

Serves: 4–6   |   Difficulty: Looks hard, secretly easy

Ingredients

For the Steak

• 1 (2–2.5 lb) London broil (top round or flank steak)
• Salt and freshly ground black pepper

For the Marinade

• 1/4 cup soy sauce
• 2 tbsp balsamic vinegar
• 2 tbsp Worcestershire sauce
• 2 tbsp olive oil
• 2 cloves garlic, minced
• 1 tsp dried rosemary or Italian seasoning
• 1–2 tsp brown sugar (optional)
• Black pepper to taste

For the Stuffing

• 2 tsp olive oil
• 1/2 small onion, finely diced
• 2–3 cloves garlic, minced
• 4 cups fresh baby spinach
• 3/4 cup shredded provolone or mozzarella
• 1/4 cup grated Parmesan (or crumbled feta)
• 1/4 cup chopped sun-dried tomatoes or roasted red peppers (optional)
• 2 tbsp fresh parsley, chopped

Step-by-Step Instructions

Step 1: Butterfly the London Broil

1. Place the steak on a cutting board. With a sharp knife, slice horizontally from one long side almost to the other, keeping the knife parallel to the board, then open it like a book.
2. Cover with plastic wrap and gently pound to an even thickness (about 1/2–3/4 inch). Don’t go full Hulk or you’ll tear it.
3. Season lightly with salt and pepper on both sides.

Step 2: Marinate

1. Whisk together soy sauce, balsamic vinegar, Worcestershire sauce, olive oil, garlic, rosemary, brown sugar, and pepper.
2. Place steak in a large zip-top bag or shallow dish and pour the marinade over.
3. Marinate in the refrigerator for at least 2 hours, ideally 4–12 hours, turning occasionally for even coverage.

Step 3: Make the Stuffing

1. In a skillet over medium heat, warm olive oil.
2. Add diced onion; sauté 3–4 minutes until soft.
3. Add garlic; cook 30 seconds until fragrant (if it burns, we pretend it never happened and start again).
4. Add spinach and cook just until wilted. Remove from heat and let cool slightly.
5. Stir in provolone/mozzarella, Parmesan, parsley, and sun-dried tomatoes or peppers if using. Taste and season lightly.

Step 4: Stuff, Roll, and Tie

1. Preheat oven to 375°F (190°C).
2. Remove steak from marinade and pat dry (very important for good browning).
3. Lay it flat, cut-side up. Spread the stuffing evenly, leaving a 1-inch border on all sides.
4. Starting from a long side, roll the steak up tightly into a log.
5. Tie with kitchen twine every 1.5–2 inches to hold the shape.

Step 5: Sear

1. Heat an oven-safe skillet (cast iron is perfect) over medium-high.
2. Add a drizzle of oil; when shimmering, sear the stuffed steak on all sides until nicely browned, about 2–3 minutes per side.

Step 6: Roast to Juicy Perfection

1. Transfer the skillet to the preheated oven.
2. Roast about 18–25 minutes, depending on thickness, until the internal temperature at the center of the roll reaches:
   • 130–135°F for medium-rare (chef favorite for tenderness)
   • 135–140°F for medium
   • Or follow USDA guidance: at least 145°F for whole-muscle beef with a 3-minute rest for safety

   Use an instant-read thermometerguessing is how great steaks die young.

Step 7: Rest and Slice

1. Let the stuffed London broil rest 10–15 minutes, tented loosely with foil.
2. Remove the twine.
3. Slice into 1/2–3/4 inch pinwheels across the grain so every slice shows off that spiral of steak, spinach, and cheese.

Pro Tips for the Best Stuffed London Broil

1. Don’t Overpack the Filling

Too much stuffing = blowouts. Aim for a thin, even layer. If you have extra filling, sauté it and serve alongside. Zero waste, zero drama.

2. Dry the Steak Before Searing

Patting the meat dry ensures a deep brown crust instead of a sad gray steam bath. Browning = flavor. Science, but delicious.

3. Respect the Rest Time

Resting lets juices redistribute so your slices stay moist instead of bleeding all over the board. It’s the cheapest “upgrade” you can give any steak. Guidance on rest and internal temps is consistent across reputable food safety and steak resources.

4. Easy Variations

• Italian-style: Add basil, provolone, and roasted red peppers.
• Greek-inspired: Spinach, feta, oregano, and olives.
• Mushroom & Swiss: Sautéed mushrooms, onions, and Swiss cheese.
• Low-carb focus: Extra spinach and herbs, less cheese, all flavor.

5. What to Serve with Stuffed London Broil

• Garlic mashed potatoes or roasted baby potatoes
• Grilled asparagus or green beans
• Mixed greens with balsamic vinaigrette
• Crusty bread to swipe up the pan juices (non-negotiable)

Common Questions (Answered Before You Panic)

Why is my London broil tough?

Usually: under-marinated, overcooked, or sliced with (not against) the grain. Give it time in the marinade, cook to the right internal temp, rest, then slice thinly across the grain for tenderness.

Can I grill a stuffed London broil?

Yesjust use indirect heat and a drip pan, sear over high heat first, then move to medium/indirect and cook covered until it hits target temperature. Turn occasionally and watch for flare-ups.

Can I prep it ahead?

Absolutely. You can marinate, stuff, roll, and tie the steak up to 24 hours in advance. Keep it chilled, well wrapped, then sear and roast before serving.

Real-World Experiences & Extra Tips for Stuffed London Broil (Extended Guide)

Once you’ve mastered the base stuffed London broil recipe, the fun really starts. Home cooks across the U.S. use this dish as their “impress everyone” move: holidays, anniversaries, Sunday dinners, or that moment you want to prove you can cook something besides takeout-level chicken.

One common experience: the first attempt looks chaotic, but slices beautifully. The roll might feel loose, the twine might be crooked, some cheese might escape onto the panand that’s fine. The crucial part is that the steak is rolled tightly enough to hold shape and cooked to the right internal temperature. Pan drippings plus melted cheese bits often become an improvised jus: splash in a little broth or red wine, scrape up the browned bits, reduce, and you’ve got a sauce that tastes intentional.

Many experienced cooks treat stuffed London broil as a flavor canvas. Entertaining a crowd that loves Italian flavors? Fill it with prosciutto, provolone, basil, and roasted peppers. Want a Midwest steakhouse vibe? Mushrooms, caramelized onions, Swiss, and a butter baste during the last minutes of roasting. Looking for something lighter? Spinach, garlic, lemon zest, fresh herbs, and just a sprinkle of Parmesan keeps it bright and not too heavy.

There’s also a practical advantage: portion control and presentation. Slicing into pinwheels means every guest gets steak and stuffing in one neat piece, instead of chasing toppings around their plate. It plates beautifully with minimal efforttwo or three spirals, a spoonful of pan sauce, simple sidesand suddenly dinner looks like it came out of a cookbook photoshoot.

Another big lesson from real kitchen use: invest in a meat thermometer. For lean cuts like London broil, 5 extra minutes in the oven can be the difference between “buttery and tender” and “shoe leather with good seasoning.” Checking at the 15–18 minute mark is smart, especially if your roast is on the thinner side. If your oven runs hot, start checking even earlier. That little bit of attention turns this from risky to reliable.

For busy households, stuffed London broil doubles as a meal-prep hero. Make two: cook one for dinner, and undercook the second slightly, chill it whole, then slice and reheat gently in a covered pan with a bit of broth over low heat on another night. The spiral slices also make decadent steak sandwiches: pile them on toasted bread with arugula, horseradish sauce, or garlicky mayo, and you’ve just invented the leftovers everyone fights over.

Finally, the emotional factor: serving stuffed London broil feels special but approachable. It’s not pretentious; it’s resourceful. You’re taking an everyday cut, layering in flavor and technique, and turning it into something worthy of a celebration. Once you see those pinwheels land on the tableand hear the inevitable “Wait, you made that?”it tends to become a repeat-performance recipe. And that’s exactly what a great stuffed London broil should be: impressive, dependable, affordable, and just a little bit dramatic.
