Garlic Butter Lettuce, Tomato & Grilled Chicken Sandwich

Sharing is caring!

This Garlic Butter Lettuce, Tomato & Grilled Chicken Sandwich began as a simple lunch idea—and quickly became a house favorite. One sunny Saturday, with fresh tomatoes on the counter and chicken in the fridge, I decided to try something new: garlic butter on thick toast.

The moment that bread hit the skillet, the smell alone told me I was onto something. Add grilled chicken, crisp Romaine, juicy tomato slices, and creamy mayo, and the result was layered, rich, and completely satisfying.

Like the bold freshness of Zesty BBQ Chicken Skewer Salad Delight or the buttery flavor bomb in 15-Minute Garlic Butter Chicken Bites, this sandwich strikes a delicious balance of warm and cool, crunchy and juicy.

Why This Recipe Works

This sandwich delivers contrast in every bite—crispy, golden garlic butter toast, tender grilled chicken, and fresh, cool vegetables. It’s the kind of meal that feels comforting but still light.

The garlic butter adds flavor and crunch without overpowering. Tomatoes bring juiciness, while lettuce adds snap. A swipe of mayo ties it all together with creamy ease. You can keep it classic or load it up with melted provolone or avocado for something richer.

Plus, it’s easy to prep, quick to assemble, and satisfying enough to stand on its own—or alongside a fresh pairing like Zesty BBQ Chicken Skewer Salad Delight or 15-Minute Garlic Butter Chicken Bites.

Ingredients & Preparation

The Flavor-Building Ingredients You’ll Need

To create a sandwich this satisfying, each ingredient has a role to play. Below is everything you’ll need to bring this together — with a few optional extras if you want to make it even more indulgent.

Here’s a quick overview:

This sandwich is also very forgiving — don’t have Texas toast? Use ciabatta or sourdough. Fresh out of garlic? Try garlic powder in a pinch, though fresh is best.

Pairing this recipe with a fresh side like Mediterranean Greek Salad with Feta and Olives really complements the flavors. And if you want something hearty and oven-roasted, the Greek Potatoes with Lemon Feta Cheese make a fantastic companion.

Tools & Smart Substitutions

You don’t need fancy equipment — just a grill, grill pan, or cast iron skillet, and a butter knife for spreading your garlic mixture. A sharp knife is key for slicing the chicken cleanly, and tongs help with flipping on the grill.

Tool Checklist:

• Grill or grill pan

• Cast iron skillet (for bread)

• Small mixing bowl (for garlic butter)

• Tongs

• Sharp knife & cutting board

Substitution Ideas:

• Bread: Brioche, ciabatta, sourdough, or sandwich rolls all work.

• Butter: Try ghee for a richer taste, or use a vegan butter alternative.

• Mayo: Swap for Greek yogurt or hummus for a lighter touch.

• Chicken: Grilled turkey breast or even rotisserie chicken for convenience.

This sandwich is all about layering texture and flavor with ingredients that are easy to find. Next, let’s get into exactly how to cook it for that golden crunch and juicy center every time.

Cooking Instructions & Tips

Step-by-Step Method for Sandwich Success

There’s something incredibly satisfying about watching a sandwich come together, especially when it sizzles with buttery garlic aroma. Let’s walk through each step to build a sandwich that’s crisp, juicy, and flavor-packed.

Step 1: Make the Garlic Butter

In a small bowl, combine ½ cup of softened unsalted butter, 2–3 cloves of minced garlic, 1 teaspoon dried Italian herbs, and ½ teaspoon red pepper flakes (optional). Mix well until everything is evenly distributed.

Tip: For deeper flavor, make this ahead and let it rest covered at room temp for 30 minutes before using.

Step 2: Prep & Grill the Chicken

Slice the 2 boneless chicken breasts horizontally to create thin cutlets. Brush each piece with olive oil, then season both sides with salt and freshly cracked black pepper.

Preheat a grill or grill pan to medium-high heat. Grill chicken for 6–7 minutes per side, or until juices run clear and internal temperature hits 165°F (74°C). Rest for 5 minutes, then slice.

Inspired by juicy grilling methods from the Lemon Garlic Butter Chicken with Creamy Parmesan Pasta, this method keeps the chicken moist and flavorful.

Step 3: Toast the Bread

Heat a cast iron skillet or large non-stick pan over medium heat. Spread a generous layer of your garlic butter mixture on one side of each of the 8 slices of bread.

Place buttered-side down into the hot skillet and toast until golden brown and crispy. You may need to work in batches.

Tip: Don’t press the bread down — let it toast gently to keep it crisp but airy.

Step 4: Assemble the Sandwich

Start with the unbuttered side of the bread facing up. Spread a light layer of mayonnaise on one slice. Add lettuce, sliced tomatoes, and your grilled chicken. Top with sliced cheese or avocado, if using.

Place the second slice of garlic toast on top (buttered side facing out), and press down gently to seal.

Step 5: Serve Immediately

Slice in half and serve hot. Each bite delivers a balance of garlic crunch, juicy chicken, and fresh vegetables.

Tips and Tricks to Perfect It

• Chicken Thickness: Thinner cutlets cook more evenly and absorb seasoning better. You can also lightly pound them to uniform thickness.

• Garlic Butter in Advance: Mix and store your butter up to 3 days ahead in the fridge — just bring it to room temp before spreading.

• Use Ripe Tomatoes: A slightly overripe tomato delivers unbeatable juiciness and sweetness.

• Avoid Over-toasting: Golden brown is perfect — too dark and the garlic will turn bitter.

• Melt Cheese Efficiently: If using cheese, layer it on hot chicken right off the grill so it melts without needing to return to heat.

Serving, Storing & Pairing

What to Serve With It

This sandwich is filling on its own, but pairing it with a light, crunchy side brings everything into balance. Because the sandwich features both warmth and freshness, the sides should echo that clean, crisp feel.

Personally, I love to serve this with a cool cucumber and tomato salad, like the one in this Cucumber and Tomatoes with Cottage Cheese recipe. The creaminess of cottage cheese and the pop of vinegary cucumber really refresh the palate between bites of buttery bread and juicy chicken.

If you’re looking to lean into the sandwich shop vibe, Avocado Feta Toast makes a beautiful companion. It mirrors the optional avocado topping while delivering extra healthy fats and bold feta flavor.

Want something even simpler? A handful of kettle chips, a fresh fruit bowl, or a pickle spear works great too. For drinks, iced tea or lemonade pairs naturally, but for something more comforting, an iced matcha latte or sparkling water with citrus brings it home.

How to Store and Reheat

These sandwiches are best served fresh—but that doesn’t mean leftovers should go to waste. Here’s how to handle them:

To Store:

• Unassembled: Store components separately. Wrap grilled chicken in foil or an airtight container in the fridge (up to 3 days).

• Garlic butter: Refrigerate for up to 1 week in a covered dish.

• Vegetables: Keep lettuce and sliced tomato dry in separate containers lined with paper towels.

To Reheat:

• Chicken: Reheat gently in a skillet with a splash of water or chicken broth, covered for 3–4 minutes.

• Garlic bread: Toast leftover slices on a dry skillet until warmed through and crispy again. Avoid microwaving or it’ll go soggy.

• Fully assembled sandwiches: Wrap in foil and reheat in a toaster oven or 350°F oven for about 10 minutes. This will revive the crunch without drying out the meat.

Frequently Asked Questions

Can I make this sandwich ahead of time?

Yes — with a little planning. Grill the chicken and prep the garlic butter in advance. Store everything separately and assemble just before serving to keep the bread crisp and the veggies fresh.

What’s the best bread for this sandwich?

Thick-cut Texas toast holds up beautifully under the garlic butter and fillings, but you can also use sourdough, ciabatta, or brioche for a softer bite. Avoid thin sandwich bread—it won’t hold the structure.

How spicy is it with the red pepper flakes?

Only mildly spicy. The flakes bring warmth without overpowering. If you prefer a completely mild sandwich, simply leave them out.

Can I use leftover chicken instead of grilling fresh?

Absolutely. Shredded rotisserie chicken or grilled chicken from a previous meal works well. Just warm it up gently before assembling.

Is there a dairy-free option?

Yes! Use a dairy-free butter alternative and skip the cheese. The garlic butter flavor still shines through, and avocado makes a great creamy swap for cheese.
