Ingredients
- Unsalted Butter: 5 tablespoons softened, divided to butter the dish and create a creamy sauce base.
- Russet Potatoes: About 2 ½ pounds peeled, providing a fluffy, tender texture that absorbs the sauce well.
- Fresh Broccoli Florets: 4 cups cut into bite-sized pieces for a crisp, vibrant vegetable element.
- Cream Cheese: 4 ounces softened, adds richness and smoothness to the sauce coating the casserole.
- Seasoned Salt: 2 teaspoons to enhance the overall flavor complexity thoughtfully.
- Black Pepper: ½ teaspoon freshly ground for mild spice and balance.
- Half & Half: ½ cup to create a luscious, creamy sauce; can be substituted as needed.
- Full-fat Sour Cream: 1 ½ cups, adding tangy creaminess and moisture to the potatoes and broccoli.
- Shredded Colby-Jack Cheese: 1 ½ cups for a melty, flavorful topping that browns beautifully in the oven.
Instructions
- Prepare and Butter the Baking Dish
-
Preheat the oven to 375°F. Use 1 tablespoon of the softened butter to generously coat the sides and bottom of a 9×13 baking dish. Buttering ensures the casserole won’t stick and adds subtle richness to the crust.
- Make the Cream Cheese Sauce
-
In a small saucepan over medium heat, melt the remaining 4 tablespoons butter with the cream cheese, seasoned salt, and black pepper. Whisk continuously to form a smooth, lump-free mixture. Then gradually incorporate the half & half, whisking until the sauce thickens. This creamy sauce binds the casserole ingredients and imparts indulgent flavor.
- Cook Potatoes and Partially Cook Broccoli
-
Place peeled potatoes in a large pot and cover with water by 2 inches. Boil until potatoes are just fork-tender, about 15 to 25 minutes depending on size. In the final 2 minutes, add broccoli florets to the pot to slightly cook and brighten their color. Use a slotted spoon to remove broccoli and set aside separately, preventing overcooking.
- Drain and Cool the Potatoes
-
Drain potatoes in a colander, allowing excess steam to evaporate and cool. Once cooled enough to handle, chop into bite-sized pieces and return to the empty pot. Cooling helps the potatoes hold their shape and prevents excess moisture from making the casserole watery.
- Combine Potatoes with Sauce and Sour Cream
-
Mix the chilled cream cheese sauce and sour cream thoroughly with the chopped potatoes, coating each piece evenly. This ensures every bite is creamy and flavorful throughout.
- Add Broccoli and Transfer to Baking Dish
-
Gently fold in the partially cooked broccoli florets to keep their bright color and texture intact. Transfer the combined mixture to the buttered baking dish, spreading evenly for uniform baking.
- Top with Cheese and Bake
-
Sprinkle shredded colby-jack cheese evenly over the top of the casserole. Bake uncovered for 25-30 minutes until the cheese is golden, fully melted, and sauce bubbles around the edges, indicating a perfectly heated casserole.
- Rest Before Serving
-
Let the casserole sit on the counter for 5 minutes after baking. This short rest allows the sauce to thicken slightly and set, making serving cleaner and improving texture.
- Use block-style, full-fat cream cheese for the best creamy texture and flavor.
- Substitute half & half with heavy cream or whole milk, but avoid low fat milks for sauce consistency.
- Yukon Gold potatoes work well if russets are unavailable, providing a slightly buttery flavor.
- Mild cheddar is an excellent alternative for colby-jack cheese topping.
- Butter the dish with a pastry brush or clean paper towel for even coverage.
Storage Tips
Store leftovers covered in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain creamy texture and avoid drying out. This casserole also freezes well; thaw before reheating.
Serving Suggestions
This casserole pairs beautifully with grilled chicken, pan-seared fish, or a fresh green salad for a full meal. Serve as a hearty side during holiday dinners or potluck gatherings for a crowd-pleaser everyone will love.
- Partially cooking broccoli before baking preserves its bright color and tender-crisp texture.
- Do not overboil potatoes to avoid mushy texture; they will finish cooking in the oven.
- Allow the casserole to rest after baking for better sauce consistency and easier serving.
