Crafting the Ultimate Steak Sandwich With Roasted Tomatoes and Creamy Anchovy Sauce
Hearty layers of tender beef, jammy veggies, and creamy zing deliver unforgettable flavor.
What makes a steak sandwich truly memorable? Is it the tender slices of perfectly cooked beef, the savor of slowly-roasted tomatoes, or that final bold flourish of tangy, creamy sauce? The answer lies in the harmonious layering of each element—the mindful pairing of textures and flavors that transform a simple sandwich into a restaurant-worthy meal. In this comprehensive guide, discover how to build a steak sandwich that’s bursting with flavor, juicy from start to finish, and guaranteed to impress at lunch, dinner, or your next gathering.
Why This Steak Sandwich Stands Out
- Slow-Roasted Tomatoes: Deep, jammy sweetness elevates every bite and balances the beef’s richness.
- Creamy Anchovy Sauce: A briny zing that highlights the steak’s beefiness and adds dimension.
- High-Quality Steak: Seared for maximum flavor and sliced thin for tender, juicy mouthfuls.
- Crusty Bread: Toasted and sturdy, supporting all the sandwich’s juicy, saucy goodness without getting soggy.
This is more than a sandwich—it’s a showcase of what happens when classic ingredients meet meticulous technique.
The Anatomy of a Superior Steak Sandwich
To assemble a steak sandwich that’s crave-worthy, each layer plays a crucial role:
- Steak: Choose a cut with robust flavor and marbling—flank, strip, or ribeye all work beautifully.
- Tomatoes: Roasted low and slow until concentrated and savory.
- Sauce: A mixture of mayonnaise, anchovy, and lemon brings briny tang and creamy richness.
- Bread: A hearty loaf like ciabatta, toasted to golden perfection.
- Greens: Optional, but peppery arugula or crisp lettuce can add a nice counterpoint.
Ingredient Guide: Selecting for Flavor and Quality
| Component | Recommendation | Notes |
|---|---|---|
| Steak | Flank, skirt, strip steak, or boneless ribeye | Look for well-marbled cuts; slice thinly against the grain for tenderness |
| Tomatoes | Plum or Roma tomatoes | Firm yet ripe; slow-roasting brings out natural sweetness |
| Sauce | Mayonnaise, anchovy fillets, garlic, lemon juice, Dijon mustard | Use good-quality anchovies packed in oil for best flavor |
| Bread | Ciabatta or crusty artisan loaf | Should be sturdy enough to hold fillings and absorb some juices |
| Greens (optional) | Arugula, watercress, or lettuce | Adds freshness and visual appeal |
Step-By-Step Recipe
Ingredients List
- 2 pounds plum or Roma tomatoes, halved lengthwise
- 2 tablespoons extra-virgin olive oil
- Kosher salt and freshly ground black pepper
- 2 tablespoons chopped fresh herbs (thyme, oregano, or basil work well)
- 1 1/2 pounds steak (flank, strip, or ribeye preferred)
- 1 ciabatta loaf, split horizontally
- 1 tablespoon canola or vegetable oil
For the Creamy Anchovy Sauce
- 1/2 cup mayonnaise
- 4 anchovy fillets, minced
- 1 garlic clove, finely grated
- 1 teaspoon Dijon mustard
- 2 teaspoons fresh lemon juice (plus more to taste)
- Freshly ground black pepper
Optional Additions
- Fresh arugula or lettuce
- Sliced red onion
- Pickled banana peppers for tang and heat
1. Slow-Roasting the Tomatoes
- Preheat the oven to 325°F (165°C).
- Arrange the tomato halves, cut side up, on a parchment-lined baking sheet.
- Drizzle with olive oil and sprinkle generously with salt, pepper, and your chosen herbs.
- Roast for about 1-2 hours, turning the tray partway through, until the tomatoes are shriveled, concentrated, and lightly caramelized.
- Let them cool while you prepare the other components.
2. Preparing the Creamy Anchovy Sauce
- In a small mixing bowl, combine the mayonnaise, minced anchovies, grated garlic, Dijon mustard, and lemon juice.
- Stir until smooth, then taste and adjust seasoning with freshly ground black pepper and extra lemon juice, if you crave more zing.
- Chill until ready to use; the flavors will meld beautifully if given a bit of time.

3. Cooking the Steak
- Bring your steak to room temperature (~30 minutes out of the fridge) and pat it dry with paper towels.
- Season it liberally with salt and pepper on both sides.
- Heat a large, heavy skillet (cast iron is ideal) over high until just smoking. Add canola oil or another high-heat oil.
- Lay the steak in the pan and sear undisturbed until a deep brown crust forms—about 3-4 minutes per side for medium-rare, depending on thickness. Flip only once.
- When done, transfer to a cutting board and let rest at least 5 minutes before slicing thinly against the grain.
4. Assembling the Sandwich
- Split the ciabatta and toast it under a broiler or in a hot oven until crisp and golden.
- Slather both cut sides of the bread with an ample layer of the creamy anchovy sauce.
- Layer slow-roasted tomatoes evenly across the bottom half.
- Shingle the sliced steak generously over the tomatoes, catching their juices.
- Add greens or other optional toppings if desired.
- Top with the other half of bread, press down gently, then slice the sandwich into manageable portions.
Expert Tips and Tricks
- Rest Your Steak: Allowing the steak to rest after searing ensures every slice remains juicy rather than losing moisture into the bread.
- Balance the Ingredients: Use enough anchovy sauce to season, but not overwhelm—the goal is umami, not fishiness.
- Slice Thinly: Whether your steak is rare or well-done, cutting it thin against the grain guarantees tenderness.
- Customize: Add pickled onions, hot peppers, or fresh herbs for brightness or heat.
Why Roasted Tomatoes Are a Must
Unlike raw tomatoes, which can water down a sandwich, slow-roasting concentrates their flavors, intensifies sweetness, and imparts a jammy quality that’s as luxurious as it is addictive.
- Enhanced Sweetness: The roasting process caramelizes natural sugars within the fruit.
- Better Texture: Roasted tomatoes ooze softly rather than gushing liquid, so they meld with other fillings instead of leaking.
- Long Shelf-Life: Make roasted tomatoes ahead and store them in the refrigerator for up to a week, ready for sandwiches, salads, or pasta.
The Secret Sauce: Anchovy Cream for Steak Sandwiches
Anchovies might seem polarizing, but handled properly, they melt into dishes and disappear into a pool of savory, briny depth. Here, the creamy anchovy sauce is far more than mayonnaise—it’s what ties the roasted tomatoes’ sweetness to the steak’s robust savor. Lean into the umami; the result is a sauce that’s punchy, tangy, and subtly complex.
- Anchovies Pack Umami: A few fillets infuse mayonnaise with a savory, almost cheese-like depth.
- Lemon and Garlic Liven Up the Flavor: Adding fresh acidity and a little heat keeps the sauce from tasting dull or heavy.
- Versatility: Leftover sauce is sensational with fries, crudités, or roasted vegetables.
Suggested Variations and Additions
- Cheese Lovers: Slide in a few slices of sharp provolone or mild Swiss right after the steak for creamy melt.
- Heat Seekers: Add pickled jalapeños, banana peppers, or a smear of spicy mustard to cut the richness.
- Herbaceous Notes: Sprinkle chopped fresh basil, parsley, or tarragon for added fragrance and color.
- Vegetarian Option: Substitute steak with thick broiled portobello mushrooms; keep the sauce and roasted tomatoes the same.
Serving and Storage Suggestions
- Serve Warm: Enjoy immediately for the best texture—hot steak and sauce soak beautifully into toasted bread.
- Make-Ahead: Tomatoes and anchovy sauce can be prepared up to a week in advance and refrigerated; assemble sandwiches just before serving.
- Storing Leftovers: Wrap tightly in foil and store in the fridge; reheat gently (sandwiches are best fresh, but they’ll still be good the next day).
Frequently Asked Questions (FAQs)
Q: Can I use another type of steak for this sandwich?
A: Absolutely—flank, skirt, strip, or ribeye are all superb. The important thing is to slice against the grain for tenderness, and season well.
Q: I’ve never used anchovies. Will the sauce taste fishy?
A: Not at all. Anchovies dissolve into the sauce and provide briny, savory depth—almost cheesy rather than fishy, especially with lemon and garlic.
Q: Can the roasted tomatoes be made ahead?
A: Yes. Roast and refrigerate them for up to 7 days. Bring to room temperature before using, or briefly rewarm to soften their texture.
Q: What bread works best?
A: A crusty, Italian-style bread like ciabatta or a rustic batard holds up to juicy steak and sauce while staying crisp on the outside.
Q: Is there a substitute for anchovies?
A: For a vegetarian twist, try finely chopped capers and a dash of soy sauce. The final flavor will be different but still punchy and savory.
