There was a time when a dependable casserole could make a hostess famous in her church circle, and this oven baked 4-ingredient chicken Florentine bake is just that kind of dish. It has the practical charm of 1970s home cooking, when a handful of pantry and freezer staples could be turned into something rich, comforting, and company-worthy. With tender chicken, spinach, a creamy sauce, and a cheesy golden top, this is the sort of supper that still feels right at home on a weeknight table or set out for company with a basket of warm rolls.
This bake is especially good with buttered egg noodles, fluffy rice, or mashed potatoes to catch every bit of that creamy sauce. If you want to round out the plate, a simple carrot dish, green beans, or a crisp salad with a tart vinaigrette balances the richness nicely. For a bridge-club style lunch, I’d serve it with fruit salad, hot rolls, and a little lemon pie afterward.
Oven Baked 4-Ingredient Chicken Florentine Bake
Servings: 6
Ingredients
4 boneless, skinless chicken breasts, about 1 1/2 to 2 pounds
1 package (10 ounces) frozen chopped spinach, thawed and well drained
1 can (10 3/4 ounces) condensed cream of chicken soup
2 cups shredded mozzarella cheese
Directions
1. Heat the oven to 375°F and lightly grease an oval glass baking dish. Pat the chicken breasts dry and arrange them in an even layer in the dish.
2. Scatter the drained spinach evenly over the chicken, tucking it around and between the pieces so every bite gets some of that Florentine flavor.
3. Spoon the condensed soup over the top and spread it gently to cover the chicken and spinach as evenly as you can.
4. Sprinkle the mozzarella evenly over the top. Bake uncovered for 35 to 45 minutes, or until the chicken is cooked through and the cheese is melted, bubbling, and lightly golden. Let it rest 5 minutes before serving.
Variations & Tips
Add a little seasoning: If your pantry allows for one or two extras, a light sprinkle of black pepper, garlic powder, or onion powder over the chicken wakes up the whole dish without changing its old-fashioned character.
Use chicken tenders: For quicker baking and easier serving, substitute chicken tenders for full breasts. Just reduce the baking time and start checking for doneness around the 25-minute mark.
Try Swiss or Monterey Jack: Mozzarella gives a mild, stretchy topping, but Swiss adds a deeper, supper-club flavor, and Monterey Jack melts beautifully if that’s what you have on hand.
Drain the spinach very well: This is the best tip of the bunch. Squeeze out as much moisture as you can from the thawed spinach so the sauce stays creamy instead of turning watery in the dish.
Make it ahead: You can assemble the casserole a few hours ahead, cover it, and refrigerate it until baking time. If it goes into the oven cold from the refrigerator, add a few extra minutes to the baking time.
