BBQ Chicken Grilled Cheese

The first time I made these sandwiches, it was actually a Tuesday night desperate attempt to use up leftover grilled chicken from a weekend cookout. My husband walked in from work and immediately asked what smelled like a barbecue joint had moved into our kitchen. Now whenever we have rotisserie chicken, these sandwiches are the inevitable follow-up.

Last summer my sister came over to help me meal prep and we ended up eating three of these between us while standing at the counter. She kept saying she would just take one bite to taste test, then another bite to make sure the seasoning was right, then suddenly half her sandwich was gone. Now she refuses to come over on sandwich prep days unless she is properly hungry.

Ingredients

• 2 cups cooked chicken breast, shredded: I have found that rotisserie chicken works beautifully here, but leftover grilled chicken gives you those gorgeous char bits that add texture
• ½ cup BBQ sauce: Use whatever brand you normally love, just know that a thicker, sweeter sauce will cling to the chicken better than runny varieties
• 8 slices sourdough bread: The sturdy texture and slight tang of sourdough makes all the difference between a sandwich that holds together and one that falls apart in your hands
• 8 slices sharp cheddar cheese: Sharp cheddar has enough bold flavor to stand up to the BBQ sauce without disappearing into the mix
• 4 slices mozzarella cheese: This is your secret weapon for that incredible cheese pull that makes grilled cheese so satisfying
• 4 tbsp unsalted butter, softened: Room temperature butter spreads evenly without tearing the bread, which I learned the hard way after many sad, ripped slices
• ½ small red onion, thinly sliced: The raw onion adds a fresh bite that cuts through all the richness, plus it looks gorgeous peeking out the sides
• ½ cup pickled jalapeños, drained: Even if you think you do not like spicy food, these add just enough vinegar and heat to make every bite interesting

Instructions

Get that chicken coated:

dump your shredded chicken into a bowl and pour the BBQ sauce over it, then use a spatula to fold it all together until every piece is evenly dressed and glossy

Prep your bread canvas:

lay out all your sourdough slices and spread a thin, even layer of softened butter on one side of each piece, then place them butter side down on your cutting board

Build the perfect stack:

start with one slice of cheddar on four bread slices, pile on that saucy chicken, add your red onion and jalapeños if you are using them, layer on the mozzarella for maximum melt, add another cheddar slice, and crown with your second piece of bread, butter side facing up

Get your pan ready:

set a large skillet or griddle over medium heat and let it get properly hot for about two minutes, you should be able to feel the heat rising when you hover your hand above it

Grill to golden perfection:

carefully transfer sandwiches to the pan and cook for 3 to 4 minutes on the first side, pressing down gently with your spatula, then flip and cook another 3 to 4 minutes until both sides are deeply golden and the cheese is oozing out the sides

The moment of truth:

transfer to a cutting board and let them rest for just 30 seconds before slicing diagonally, which helps everything set slightly so your cheese does not all run out

My oldest son started requesting these for his birthday dinner instead of going out to restaurants, which honestly feels like the highest compliment a kid can pay to a sandwich. He says restaurant grilled cheese never tastes as good as the ones we make at home together while listening to his favorite playlist.

Making It Your Own Way

Sometimes I swap in pepper jack for the cheddar when everyone is feeling adventurous, and the extra kick takes these to a completely different level. I have also made them with gouda when I wanted something smokier, and that combination was absolutely incredible in ways I did not expect.

What To Serve Alongside

A cold, crisp coleslaw cuts through the richness perfectly, and I always make extra because people inevitably want seconds. Pickles on the side are non negotiable in our house, their vinegar brightness balances all that cheesy, saucy goodness so nicely.

Timing And Prep Like A Pro

I always shred my chicken and mix it with the BBQ sauce about an hour before cooking, which gives the flavors time to meld together beautifully. Having everything prepped and laid out assembly line style makes the actual cooking feel so much smoother.

• Wrap sandwiches in foil and keep them in a warm oven if you are feeding a crowd
• These reheat surprisingly well in a toaster oven, though they are best fresh
• Cutting sandwiches with a serrated knife keeps the cheese from getting dragged all over the place

These sandwiches have become our go to comfort food for rainy weekends and celebratory weeknight dinners alike. Honestly, there is something magical about that combination of smoky, tangy, creamy, and crunchy all in one bite.

Recipe Help & Support

→ What type of bread works best?

Sourdough bread provides ideal structure and tangy flavor that complements the BBQ chicken. Its sturdy texture holds up well to griddling without getting soggy.

→ Can I use rotisserie chicken?

Absolutely. Rotisserie chicken adds extra depth and saves prep time. Simply shred the meat and toss with your favorite BBQ sauce before assembling.

→ How do I get perfectly melted cheese?

Use medium heat and cook 3–4 minutes per side. The gentle heat allows cheese to melt completely while bread turns golden brown and crispy.

→ What cheese combinations work well?

Sharp cheddar and mozzarella create excellent flavor and melt. Pepper jack adds spicy kick, or try provolone for a milder, creamier result.

→ What sides complement this sandwich?

Crisp coleslaw, dill pickles, or a simple green salad balance the rich flavors. For beverages, try an IPA, crisp lager, or sweet tea.
