This oven baked 3-ingredient chicken fontainebleau is the kind of dependable company dish that feels a little special without asking much from the cook. It bakes up rich, creamy, and beautifully golden, making plain chicken taste like something you fussed over for hours. Recipes like this became favorites at family gatherings and garden lunches because they were easy to assemble ahead, baked in one dish, and always came to the table looking comforting and elegant.
Serve this chicken with fluffy rice, buttered egg noodles, mashed potatoes, or a piece of crusty bread to catch every bit of the creamy sauce. For a lighter plate, add steamed green beans, roasted asparagus, or a crisp garden salad with a simple vinaigrette. If you are serving guests, a fruit salad or a chilled pasta salad rounds things out nicely without competing with the richness of the chicken.
Oven Baked 3-Ingredient Chicken Fontainebleau
Servings: 6
Ingredients
2 1/2 to 3 pounds boneless, skinless chicken breasts or chicken tenders
1 cup sour cream
1 packet dry onion soup mix
Directions
1. Preheat the oven to 350°F and lightly grease a rectangular baking dish.
2. Arrange the chicken in a single layer in the prepared dish.
3. In a medium bowl, stir together the sour cream and dry onion soup mix until smooth and fully combined.
4. Spread the sour cream mixture evenly over the chicken, covering the pieces well.
5. Bake uncovered for 40 to 50 minutes, or until the chicken is cooked through and the sauce is bubbling and lightly browned around the edges.
6. Let the dish rest for 5 minutes before serving so the sauce settles slightly. Spoon plenty of sauce over each portion when serving.
Variations & Tips
For extra richness: Use full-fat sour cream for the creamiest sauce and best texture. Reduced-fat sour cream can work, but the sauce may be a little thinner as it bakes.
For picky eaters: Chicken tenders are a nice choice because they cook evenly and are easy to serve. If the onion flavor seems too strong for little ones, mix in just three-quarters of the soup packet first and taste the sauce before using the rest.
Make it a full casserole: Add a layer of cooked rice or egg noodles to the baking dish before topping with the chicken and sauce if you want a one-pan supper. Just be sure the starch is already cooked so everything finishes at the same time.
Cooking tip: If your chicken breasts are very thick, cut them in half horizontally or pound them to an even thickness so they bake more evenly and stay tender.
Easy flavor change: A light sprinkle of paprika or chopped parsley over the top before serving gives the dish a little color and makes it look especially pretty for guests, while still keeping the recipe simple.
