Tupperware Party Bake: Just 3 ingredients. I make it when I want a stress-free dinner before the long weekend festivities begin.

This 3-ingredient oven party bake is the kind of no-fuss dinner that earns a permanent place in a busy family’s meal rotation. Inspired by the easy, crowd-feeding casseroles that were popular at mid-century potlucks and Tupperware gatherings, it leans on simple pantry staples to turn a tucked-away baked protein into something creamy, savory, and comforting with hardly any prep at all.

Serve this hearty bake with buttered egg noodles, fluffy rice, or mashed potatoes to soak up the rich sauce. For a little balance, I like to add a crisp green salad, steamed green beans, or simple glazed carrots, and if you’re feeding a bigger group before a holiday weekend, a basket of warm rolls makes it feel especially welcoming.

3. Spoon the condensed cream of mushroom soup evenly over the chicken, spreading it gently so the meat is mostly covered.

4. Sprinkle the crushed crackers all over the top to make a full, even layer.

5. Bake for 40 to 50 minutes, until the chicken is fully cooked and the topping is deeply golden, bubbling around the edges, and crisp on top. Let it rest for 5 minutes before serving.

Variations & Tips

Swap the protein: Boneless pork chops work nicely here too, as long as they are arranged in a single layer and baked until fully cooked. If the pieces are thicker, allow a little extra oven time.

For extra crunch: If your family loves a crisp topping, save a small handful of cracker crumbs and add them during the last 10 minutes of baking so they stay especially toasty.

Make it cozy with sides: This bake is rich and savory, so mild sides like rice, noodles, or mashed potatoes help round out the plate without competing with the casserole.

Picky eater tip: For kids or anyone who prefers familiar flavors, keep the recipe exactly as written the first time. Its creamy sauce and buttery topping are usually easy to win people over with.

Pan rest matters: Letting the casserole sit for a few minutes after baking helps the sauce settle a bit, making it easier to serve neat portions.
