This oven baked 4-ingredient chicken cacciatore casserole is the kind of recipe you’d expect to find in a well-loved, splattered recipe box from the early 1960s. It uses just a few pantry staples, bakes up in a simple glass dish, and fills the house with that cozy, tomato-and-herb aroma that makes everyone wander into the kitchen asking when dinner is ready. The idea is very much in the spirit of those mid-century “keeper” casseroles: minimal fuss, family-friendly, and hearty enough to feed a hungry crowd on a busy weeknight.
Serve this casserole straight from the baking dish with a big wooden spoon, letting everyone scoop out the tender chicken, peppers, and rustic red sauce. It’s wonderful over hot buttered egg noodles, spaghetti, or fluffy white rice to soak up the juices. Add a simple green salad with a tangy vinaigrette or some steamed green beans on the side. If you have time, warm up a loaf of crusty bread or garlic toast to swipe through the bottom of the pan and catch every last bit of sauce.
Oven-Baked 4-Ingredient Chicken Cacciatore CasseroleServings: 4-6
Ingredients
2 to 2 1/2 pounds bone-in chicken pieces (thighs and drumsticks, skin-on or skinless)
1 large green bell pepper, seeded and sliced into thin strips
1 (28-ounce) can crushed tomatoes or tomato puree
1 (0.7- to 1-ounce) packet dry Italian salad dressing mix
Optional: 1 tablespoon olive oil or softened butter for greasing the baking dish
Optional: Salt and black pepper to taste (if your seasoning packet is low-sodium)
Directions
Preheat your oven to 375°F (190°C). Lightly grease an oval glass baking dish with olive oil or butter if you’d like easier cleanup.
Pat the chicken pieces dry with paper towels. If desired, lightly season both sides with a little salt and black pepper, keeping in mind that the Italian dressing mix may already contain salt.
Arrange the chicken pieces in a single layer in the greased glass baking dish, meaty side up. It’s fine if they fit snugly; just avoid stacking them.
Scatter the sliced green bell pepper evenly over and around the chicken pieces, tucking some strips down between the pieces so they’ll soften in the sauce.
In a medium bowl, stir together the crushed tomatoes and the packet of dry Italian salad dressing mix until well combined. Taste a small spoonful; if it needs more salt or pepper, add a pinch now and stir again.
Pour the tomato and seasoning mixture evenly over the chicken and peppers, making sure everything is coated and the chicken is mostly nestled into the sauce. Use the back of a spoon to gently spread the sauce if needed.
Cover the baking dish tightly with foil. Place the dish on the middle rack of the preheated oven and bake for 45 minutes.
After 45 minutes, carefully remove the foil (watch for steam). Spoon some of the sauce over the tops of the chicken pieces. Return the uncovered dish to the oven and bake for another 20 to 30 minutes, or until the chicken is very tender and cooked through. The internal temperature should reach at least 165°F (74°C) in the thickest part without touching the bone.
Once done, the sauce will be bubbly and slightly thickened, and the chicken should look very moist and easy to pull apart with a fork. Let the casserole rest on the counter for about 5 to 10 minutes before serving so the juices settle a bit.
To serve, use a wooden spoon to scoop generous portions of chicken, peppers, and plenty of rustic red sauce over pasta, rice, or noodles. Spoon extra sauce from the edges of the dish over each serving.
Variations & Tips
For picky eaters, you can swap the green bell pepper for red or yellow peppers, which are a bit sweeter, or dice the peppers smaller so they ‘hide’ more easily in the sauce. If your family really dislikes peppers, you can leave them out and still have a tasty, saucy chicken dish. For a slightly richer version, add a handful of sliced mushrooms (fresh or well-drained canned) to the dish along with the peppers—this keeps the feel of classic cacciatore while still being simple. You can also stir in a small handful of sliced black olives during the last 10 minutes of baking if your crew enjoys them. If you prefer boneless, skinless chicken thighs, they work well too; just start checking for doneness around the 35–40 minute mark once uncovered, as they can cook a bit faster and may not need the full time. For a little extra old-fashioned comfort, sprinkle the finished casserole with a small handful of shredded mozzarella or Parmesan right after it comes out of the oven and let it melt while the dish rests.
Food safety tips: Always wash your hands, cutting board, and any utensils that have touched raw chicken with hot, soapy water before using them on other foods. Make sure the chicken reaches an internal temperature of at least 165°F (74°C); use an instant-read thermometer inserted into the thickest part of the meat, avoiding the bone. If you use bone-in pieces, check a couple of different pieces to be sure they’re all fully cooked. Leftovers should be cooled slightly, then stored in a covered container in the refrigerator within 2 hours and eaten within 3 to 4 days. Reheat leftovers until steaming hot all the way through before serving.
