How to Make Grilled Steak & Avocado Sandwich Recipe
Step 1: Prepare the Steak
Start by heating your grill or grill pan to medium-high heat to get it nice and hot. Drizzle the steaks with olive oil and season them generously with salt and pepper on both sides. This step is all about building the foundation of flavor while ensuring your steak gets that perfect sear.
Step 2: Grill the Steaks
Place the steaks on the grill and cook for about 4-6 minutes per side depending on thickness and your preferred doneness. For a juicy medium-rare, aim for an internal temperature between 130-135°F (54-57°C). Cooking the steak just right is key because it’s the star of this Grilled Steak & Avocado Sandwich Recipe.
Step 3: Let the Steak Rest and Slice
Take the steaks off the grill and let them rest for 5 minutes. This resting period locks in the juices so every bite stays tender and flavorful. Then slice the steak thinly against the grain to ensure maximum tenderness.
Step 4: Make the Sauce
While the steak rests, mix the mayonnaise, Dijon mustard, lemon juice, and hot sauce in a small bowl until smooth and blended. This sauce is simple but packs a punch—adding creaminess, tang, and just a touch of heat that elevates the entire sandwich.
Step 5: Toast the Bread
Toast your bread slices either on the grill or in a toaster until they’re golden brown and crispy. This step adds a satisfying crunch to balance out the creamy avocado and juicy steak slices.
Step 6: Assemble the Sandwich
Spread the tangy sauce generously on both slices of toasted bread. Layer the bottom slice with fresh arugula or mixed greens, then add tomato slices followed by the steak strips and avocado slices. Top with thinly sliced red onion and a sprinkle of salt and pepper for an extra burst of flavor.
Step 7: Finish and Serve
Place the second slice of bread on top, press gently, and slice the sandwich in half. Serve immediately so you can enjoy the perfect contrast of warm steak and toasted bread with cool, creamy avocado.
How to Serve Grilled Steak & Avocado Sandwich Recipe
Garnishes
Adding fresh herbs like cilantro or parsley can brighten up the sandwich, while a squeeze of extra lemon juice amps up the freshness. Thin slices of jalapeño or a drizzle of extra hot sauce can also bring a spicy kick for those who love heat.
Side Dishes
This sandwich pairs wonderfully with simple sides like crispy sweet potato fries, a light mixed green salad, or even a tangy coleslaw. These sides complement the richness of the steak and avocado without overpowering it.
Creative Ways to Present
For a crowd-pleasing presentation, cut the sandwich into smaller sliders and serve on a wooden board with toothpicks. Or wrap it tightly with parchment paper for a portable lunch that maintains all the delicious layers intact.
Make Ahead and Storage
Storing Leftovers
If you have leftover steak or sandwich halves, wrap them tightly in plastic wrap or use an airtight container. Store in the refrigerator and eat within 2 days for the best taste and texture.
Freezing
This sandwich is best enjoyed fresh, but you can freeze leftover cooked steak separately (not assembled) for up to 3 months. Avocado and bread do not freeze well without affecting texture.
Reheating
Reheat leftover steak gently in a skillet over low heat or in the microwave with care to avoid overcooking. Toast the bread fresh before assembling again to keep that perfect crunch.
FAQs
Can I use other cuts of steak for this sandwich?
Absolutely! While ribeye or sirloin are recommended for their tenderness and flavor, flank or skirt steak can work well if sliced thin and cooked properly.
Is there a vegetarian version of the Grilled Steak & Avocado Sandwich Recipe?
For a vegetarian twist, try replacing the steak with grilled portobello mushrooms or marinated tofu for a similar meaty texture and smoky flavor.
Can I make the sauce ahead of time?
Yes, the sauce can be prepared up to 2 days in advance and stored in the refrigerator. This actually helps the flavors meld together beautifully.
What’s the best bread choice for this sandwich?
Sturdy breads like sourdough, ciabatta, or whole wheat are ideal because they hold up well to the juicy ingredients without becoming soggy.
How do I know when the steak is done to medium-rare?
Using a meat thermometer is the most reliable way; target an internal temperature of 130-135°F (54-57°C). Otherwise, feeling the steak with your hand or using the “finger test” method can help gauge doneness.
