Leftover Grilled Chicken Casserole with Broccoli and Swiss Cheese
Golden Swiss cheese melts between juicy cherry tomatoes and tender pieces of grilled chicken in this colorful casserole. Among leftover grilled chicken casserole recipes, this one keeps things light with broccoli and lentils while still delivering that cozy, cheesy finish. The chicken’s grilled edges bring a savory flavor that makes every forkful more interesting.
Why This Recipe Works
The lentils give this casserole a hearty base without making it heavy. Meanwhile, broccoli adds texture, and cherry tomatoes soften just enough to release a little juice. That moisture works especially well with sliced grilled chicken. Swiss cheese melts through the warm ingredients, bringing everything together without hiding the chicken’s grilled flavor.

What You’ll Need
| Ingredient | Amount |
|---|---|
| Leftover grilled chicken, fully cooked | 2 cups, chopped |
| Frozen Italian-style lentil and vegetable blend with broccoli | 1 package (11.5 oz) |
| Cherry tomatoes | 10, halved |
| Swiss cheese | 3 slices, diced |
Choose an Italian-style lentil and vegetable blend that contains broccoli. The lentils should become tender when heated, while the broccoli should hold its shape.
Cut the leftover grilled chicken into bite-sized pieces. Try to keep some of the browned edges on each piece. Those grilled surfaces add character to the finished casserole.
Halve the cherry tomatoes so their juices can mingle with the warm lentils. Leave the Swiss cheese in small pieces so it melts across the casserole instead of forming one thick patch.
Reheating Tip
A covered microwave-safe casserole dish works well for gently warming leftover grilled chicken. Arrange the chopped chicken over the hot lentil mixture, cover with a microwave-safe lid, and heat in short intervals until thoroughly hot.
Stir gently between intervals to distribute the heat. The warm vegetables help surround the chicken with moisture, while the lid limits moisture loss. Avoid leaving the chicken exposed to prolonged microwave heating, which can make the edges chewy.
A microwave-safe glass casserole dish with a fitted lid is especially useful here. It keeps the ingredients together during heating and lets you check the cheese and chicken without transferring everything between dishes.
How to Make Leftover Grilled Chicken Taste Good Again
Grilled chicken often has lovely browned edges, but its seasoning can seem less noticeable after refrigeration. The trick here is to distribute those flavorful edges throughout the lentil mixture.
Use a sharp chef’s knife to cut the chicken across the grain into small, even pieces. This gives you tender bites while keeping the grilled surfaces visible.
Next, mix the chicken gently with the warm Italian-style vegetables before adding the cheese. The seasoned lentils coat the pieces lightly, while the tomato juices add a fresh note. Finally, the Swiss cheese brings a mild, buttery richness that complements the grilled flavor.
The goal is to keep the chicken recognizable, not bury it under cheese.
How to Make Leftover Grilled Chicken Casserole
Step 1: Prepare the Grilled Chicken
Remove 2 cups of leftover grilled chicken from the refrigerator.
Using a sharp chef’s knife, chop the chicken into bite-sized pieces. Aim for fairly even pieces so they warm at a similar rate.
Keep the grilled edges intact where possible. Set the chicken aside while you prepare the vegetables.
Step 2: Heat the Lentil and Vegetable Blend
Place the 11.5-ounce package of frozen Italian-style lentil and vegetable blend in the microwave.
Heat according to the package directions, approximately 5 minutes, until the lentils and broccoli are hot.
Carefully transfer the mixture to a microwave-safe casserole dish. Stir gently to spread the lentils and broccoli evenly.
Step 3: Add the Leftover Grilled Chicken
Arrange the 2 cups of chopped leftover grilled chicken over the hot lentil mixture.
Gently fold the chicken into the vegetables so the pieces are evenly distributed.
Keep the chicken near the surface as well. This allows the grilled pieces to remain visible beneath the melted cheese.
Step 4: Add the Tomatoes and Swiss Cheese
Scatter the 10 halved cherry tomatoes across the casserole.
Next, distribute the 3 diced slices of Swiss cheese over the chicken and vegetables.
Try to spread the cheese between the chicken pieces. Small gaps allow the red tomatoes, green broccoli, and grilled chicken to show through.
Step 5: Heat Until the Cheese Melts
Cover the casserole with a microwave-safe lid.
Microwave on medium power for approximately 2 minutes. Check the casserole, then continue heating in 30-second intervals as needed until the chicken and vegetables are thoroughly hot and the cheese has melted.
Let the casserole stand, covered, for 2 minutes before serving.
The finished casserole should have soft, melted Swiss cheese, tender chicken, and warm lentils. The tomatoes should remain juicy rather than collapsing completely.
Conclusion
A forkful of this casserole brings together savory grilled chicken, tender lentils, bright tomatoes, and soft Swiss cheese. The broccoli gives each bite a little structure, while the melted cheese settles into the spaces between the ingredients. It’s a cheerful, colorful way to give leftover grilled chicken a proper place at the dinner table.
