Prepare the steak: Bring the ribeye to room temperature and pat dry. Season both sides with salt and black pepper.
Sear and baste: Heat olive oil in a skillet over medium-high heat. Sear the steak until a crust forms, quickly searing the edges as well. Reduce heat, add butter, thyme, and a halved garlic bulb, and baste the steak with the butter for a short time.
Rest the meat: Transfer the steak to a cutting board, tent loosely with foil, and rest 5–8 minutes so the juices redistribute.
Cook the vegetables: In the same skillet, sauté sliced onion until soft, then briefly char bell pepper strips until they have a bit of color.
Slice and assemble: Slice the steak thinly against the grain. Spread pesto aioli on halved ciabatta, add garlic if desired, then layer onions, peppers, steak, smoked cheese, and arugula. Close and serve immediately.
Substitutions and Variations
Gluten-free: Use gluten-free rolls or bread.
Different cuts: Try strip steak, skirt, flank, or filet; or use grilled chicken for a leaner option. Leftover steak reheated gently also works.
Fats: Replace butter with olive or vegetable oil if preferred.
Add heat: Include chipotle, chili powder, or sliced jalapeños for spice.
Cheese swaps: Provolone, Swiss, gouda, sharp cheddar, or blue cheese give different flavor profiles.
Condiment swaps: Garlic aioli, chipotle mayo, Dijon mustard, chimichurri, or plain pesto are all tasty alternatives.
Bread options: Baguette, hoagie rolls, soda bread, or toasted sourdough are great substitutes.
Veggies: Add mushrooms or zucchini, or keep it classic with just peppers and onions.
Greens: Baby arugula is ideal, but spinach, lettuce, or microgreens can be used.
Serving Suggestions
Starters: A light soup or salad pairs well before the sandwich.
Sides: Classic sides include onion rings, sweet potato wedges, fries, or a wedge salad.
Dessert: Finish with a simple fruit-based dessert or a creamy parfait for balance.
How to Store
Best eaten fresh: These sandwiches are at their best when made and served immediately. Refrigeration and reheating can toughen the steak.
Freezing: Not recommended, as freezing changes the texture of the bread and meat.
Top Tips
Bring steak to room temperature: Let it sit 30 minutes before cooking for even doneness.
Sear well: A quick, high-heat sear locks in juices—use tongs to turn and sear the edges.
Rest before slicing: Resting the steak keeps it juicy. Use the resting time to sauté the vegetables in the same pan to capture all the flavors.
