‘Potluck staple’: Only 4 ingredients. I’ve brought it so many times it’s basically my signature.

This 4-ingredient cheesy broccoli and chicken bake is what I think of as a modern, no-fuss cousin of classic Midwestern casserole cooking. Instead of dirtying a stack of dishes, everything nestles together in a foil-lined pan: sliced chicken breasts, bright green broccoli, a generous blanket of cheese, and a simple creamy binder. It borrows the spirit of old-school church potlucks and weeknight hot dishes—hearty, comforting, and family-friendly—but trims down the ingredient list and cleanup. You might make this on a busy weeknight when you want something warm and satisfying without hovering over the stove, or when you need an easy, crowd-pleasing main that can be prepped ahead and baked off just before dinner. Baked in foil, it emerges from the oven looking like a cozy, cheesy casserole: neatly sliced chicken, tucked-in broccoli florets, and a golden, bubbly top that’s just crisp enough while staying gooey underneath.

This bake is rich and comforting, so I like to pair it with something that adds contrast in texture and freshness. A simple green salad with a tangy vinaigrette cuts through the creaminess nicely, or you can serve it alongside roasted potatoes or a pot of buttered egg noodles to soak up the extra cheesy sauce. Steamed rice—white, brown, or even a wild rice blend—also works well if you want to stretch the dish for more servings. If you’re feeding a crowd, add a crusty baguette or garlic bread and a bowl of lightly dressed shredded cabbage or slaw to keep the plate balanced and not overly heavy.

4-Ingredient Cheesy Broccoli and Chicken Bake in Foil

Servings: 4

Ingredients

1 1/2 pounds boneless, skinless chicken breasts (about 3–4 small breasts)
3 cups small broccoli florets (fresh or thawed from frozen, well drained)
2 cups shredded cheese (such as mild cheddar or a cheddar–mozzarella blend)
1 cup prepared creamy sauce (such as ranch dressing, Alfredo sauce, or condensed cream of chicken soup thinned with a splash of water or milk)
Kosher salt and freshly ground black pepper, to taste (optional but recommended)
1–2 teaspoons olive oil or nonstick spray, for the foil

Directions

Preheat your oven to 400°F (200°C). Line a rectangular baking dish or sheet pan with heavy-duty aluminum foil, leaving some overhang so you can fold the edges up slightly to form a shallow tray. Lightly grease the foil with olive oil or nonstick spray.

Prepare the chicken: Pat the chicken breasts dry with paper towels. Slice each breast crosswise into 1/2-inch-thick pieces, keeping the slices from each breast together so you can reassemble them in neat rows. Season both sides of the slices lightly with salt and pepper if using.

Arrange the chicken: Place the sliced chicken in rows in the center of the foil-lined pan, slightly fanning the pieces so they resemble the look of whole breasts sliced but still nestled together. Leave some space between and around the rows for the broccoli and cheese mixture.

Add the broccoli: Scatter the broccoli florets around and between the chicken rows, tucking some pieces gently into the gaps so the florets are nestled in close contact with the chicken. This arrangement helps the broccoli cook evenly and soak up the cheesy sauce.

Mix the cheese and sauce: In a medium bowl, combine the shredded cheese and the creamy sauce. Stir until you have a thick, spoonable mixture. Taste and adjust seasoning with a pinch of salt and pepper if desired, remembering that cheese and some sauces are already salty.

Top the chicken and broccoli: Spoon the cheesy mixture evenly over the chicken slices and broccoli, focusing on coating the tops and allowing some to fall between the pieces. You want a visible layer of cheese on top that will melt and brown, while some of the sauce seeps down to create that creamy, casserole-like texture.

Shape the foil tray: Fold up the edges of the foil slightly to contain any bubbling sauce, but leave the top fully open so the cheese can brown. The foil should form a shallow tray that supports the ingredients and makes cleanup easy.

Bake: Transfer the pan to the preheated oven and bake for 22–28 minutes, or until the chicken is cooked through (an instant-read thermometer should register 165°F/74°C in the thickest pieces) and the broccoli is tender. The cheese should be fully melted and starting to bubble.

Brown the top: For a slightly crisper, more golden top like a classic casserole, switch the oven to broil for 2–4 minutes at the end of cooking. Watch closely so the cheese develops small browned spots without burning.

Rest and serve: Remove the bake from the oven and let it rest for 5 minutes so the sauce thickens slightly. Carefully lift or slide the foil tray onto a wooden board or heatproof surface. Serve the sliced chicken and broccoli with plenty of the cheesy sauce spooned over each portion.

Variations & Tips

To keep this true to its 4-ingredient spirit, think of variations as simple swaps rather than additions. For the cheese, you can use Monterey Jack, Colby-Jack, pepper Jack (for a little heat), or even a smoked cheddar for deeper flavor; just keep the total amount around 2 cups so the texture stays right. For the creamy component, ranch dressing yields a tangy, familiar flavor, while Alfredo sauce gives a richer, more Italian-leaning profile, and thinned condensed cream of chicken soup leans into classic Midwestern casserole territory. If you prefer darker meat, boneless, skinless chicken thighs work well and stay very juicy—just trim excess fat and slice them into strips. You can also swap the broccoli for cauliflower or use a mix of the two, adjusting the size of the florets so they cook at the same rate as the chicken. For more pronounced browning, reserve 1/2 cup of the shredded cheese, bake the dish covered loosely with foil for the first 15 minutes (to keep moisture in), then remove the cover, sprinkle on the reserved cheese, and finish baking until bubbly and golden. If your broccoli is very firm (especially thick fresh florets), briefly blanch it in boiling salted water for 2–3 minutes and drain well before adding; this ensures the florets turn tender by the time the chicken is done without overcooking the meat.
