This 4-ingredient oven jubilee casserole has that retro, pantry-friendly charm that makes busy weeknights feel manageable. It’s the kind of hearty baked dinner you can assemble hours ahead, tuck into the fridge, and bake when everyone is finally home. Inspired by classic 1970s casseroles, this version keeps things simple: a concealed baked protein under a creamy, savory layer with a deeply comforting golden top.
Serve this casserole with something fresh and simple to balance the richness, like a crisp green salad, steamed green beans, or sliced summer tomatoes with a little salt and pepper. If you want to stretch it further, add warm dinner rolls, buttered peas, or a scoop of fluffy rice to catch every bit of the creamy sauce.
4-Ingredient Oven 1970s Jubilee Casserole
Servings: 6
Ingredients
2 cups cooked shredded chicken
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
2 cups crushed butter crackers
Directions
1. Preheat the oven to 350°F and lightly grease a medium ceramic baking dish.
2. In a large bowl, stir together the condensed cream of mushroom soup and sour cream until smooth.
3. Fold in the shredded chicken until evenly coated.
4. Spread the mixture evenly into the prepared baking dish, then sprinkle the crushed butter crackers evenly over the top to fully cover the filling.
5. Bake for 30 to 35 minutes, until hot and bubbling around the edges and golden brown on top. Let it rest for 5 to 10 minutes before serving.
Variations & Tips
Make-ahead tip: Assemble the casserole up to 8 hours ahead, cover, and refrigerate. When you’re ready to bake, let it sit at room temperature for about 20 minutes so the dish warms slightly and bakes more evenly.
Protein swap: Cooked turkey works beautifully here if you have leftovers to use up. It gives the casserole the same cozy feel and is especially practical after a holiday weekend.
Crunchier topping: For a little more texture, bake the casserole uncovered on the upper oven rack for the last 5 minutes. Keep a close eye on it so the cracker topping turns deeper golden without burning.
Soup option: If cream of mushroom isn’t your favorite, condensed cream of chicken can be used instead. The flavor will be a little milder but still rich and comforting.
