The chipotle peppers in adobo lend a smoky heat that’s mellowed by mayonnaise, while the mozzarella melts into the warm focaccia for gooey, comforting bites. The tomato and basil brighten every mouthful, and the red onion gives a crisp, tangy contrast. It’s quick to assemble if you have cooked chicken on hand and scales easily for a crowd.

Ingredients

▢½cupmayonnaise(*)
▢3chipotle peppers in adobo sauce(from 1 can**)
▢1loaffocaccia bread(cut into quarters and sliced in half horizontally)
▢2cooked chicken breasts(sliced***)
▢8ouncesfresh mozzarella cheese(sliced)
▢1tomato(sliced)
▢½red onion(thinly sliced)
▢10fresh basil leaves(chopped)

Notes on ingredients

All quantities are listed exactly as used in the recipe. The mayonnaise and chipotle peppers form the sandwich spread; use mild or medium chipotle peppers if you prefer less heat. The focaccia should be cut into quarters and split horizontally so each quarter becomes a top and bottom. Use pre-cooked chicken breasts for speed — roast, poach, or grill according to your preference, then slice. Fresh mozzarella is best for melting, and ripe tomato and thinly sliced red onion add fresh texture. Chop the basil leaves just before assembling to preserve aroma.

Preparation overview

We’ll make the chipotle mayo, assemble the sandwiches with sliced chicken and toppings, and toast the assembled sandwiches until the cheese is melted and the bread is golden. The steps below follow the original order but rewrite each direction into clear, numbered instructions for a smooth cooking experience.

Step-by-step directions

Make the chipotle mayonnaise. In a small bowl, combine ▢½cupmayonnaise(*) and ▢3chipotle peppers in adobo sauce(from 1 can**). Use a fork or small whisk to mash and blend the peppers into the mayonnaise until the mixture is smooth and evenly seasoned. Taste and adjust the blend slightly if you want more or less heat.
Prepare the focaccia. Take ▢1loaffocaccia bread(cut into quarters and sliced in half horizontally) and place the bottom halves on a clean work surface or baking sheet. If your focaccia is very thick, you may press down slightly to flatten it for even toasting.
Spread the chipotle mayonnaise on the bread. Spoon a generous layer of the chipotle mayonnaise onto the cut surface of each bottom focaccia half. Spread evenly so every bite will have flavor.
Layer the sandwich components. Arrange ▢2cooked chicken breasts(sliced***) over the mayo on each bottom half, distributing the slices so the protein covers the bread evenly. Next, place ▢8ouncesfresh mozzarella cheese(sliced) atop the chicken in a single layer for good melting. Add ▢1tomato(sliced) in slightly overlapping slices over the cheese, followed by a light scattering of ▢½red onion(thinly sliced) for brightness. Finish the layer with ▢10fresh basil leaves(chopped) spread across the tomato and cheese.
Top with the focaccia lids. Place the top halves of the focaccia over each assembled bottom, pressing gently so the layers settle together.
Toast the sandwiches. Heat a skillet or griddle over medium heat, or preheat an oven to 375°F (190°C) if you prefer baking. If using a skillet, place the sandwiches in the pan and press lightly with a spatula. Toast for about 3–5 minutes per side, or until the focaccia is golden and the mozzarella has started to melt. If baking, place the assembled sandwiches on a baking sheet and bake for 8–12 minutes, until the cheese is melted and the bread is warmed through. Monitor closely so the bread doesn’t over-brown.
Rest and slice. Remove the toasted sandwiches from the heat and let them sit for 1–2 minutes. This brief rest helps the cheese set just enough for clean slicing. Slice each quartered sandwich in half diagonally or vertically, depending on how you like to serve it.
Serve immediately. Serve the Toasted Frontega Chicken (Panera Bread Copycat) warm, paired with a simple green salad, chips, or a cup of soup. The sandwich is best enjoyed fresh when the cheese is still melty and the focaccia has a crisp exterior.

Tips and variations

For extra flavor, warm the sliced chicken briefly in the skillet before assembling so it contributes heat to melt the mozzarella faster.
If the chipotle peppers are very spicy for your taste, start with two peppers and add more after tasting the mayo mixture.
Substitute smoked or oven-roasted chicken breasts if you want a deeper smoky profile. Keep the quantity at ▢2cooked chicken breasts(sliced***).
To make this sandwich vegetarian, replace the chicken with thick slices of roasted portobello or eggplant and keep the rest of the ingredients the same.
To crisp the focaccia more, brush a little olive oil on the cut surfaces before toasting.

Make-ahead and storage

If you want to prepare components ahead, mix the chipotle mayonnaise up to two days in advance and store it in an airtight container. Cook and slice the chicken earlier in the day and refrigerate. Assemble and toast the sandwiches just before serving for the best texture and flavor. Leftovers can be wrapped tightly and refrigerated for up to 2 days; reheat in a skillet or oven to refresh the bread and melt the cheese again.

Nutrition snapshot

This Toasted Frontega Chicken (Panera Bread Copycat) is rich with protein from the cooked chicken and satisfying fats from the mayonnaise and mozzarella. Fresh tomato, onion, and basil add vitamins and bright flavors. Exact nutrition depends on the specific brands and sizes you use, so calculate using your own ingredients if you need precise numbers.

Serving suggestions

Keep the sides light to let the sandwich shine. A crisp green salad with lemon vinaigrette, a cup of vegetable soup, or a side of roasted sweet potato wedges pairs beautifully. For a picnic, slice the toasted focaccia sandwich into smaller portions and pack the chipotle mayonnaise separately if you’re worried about sogginess; brush it on just before serving.
