Ingredients (3 Only!)

2 lbs (about 6 cups) diced potatoes — peeled or unpeeled
1 cup ranch dressing
1 ½ cups shredded cheddar cheese, divided

Instructions

Preheat: Set oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Mix: In a large bowl, combine diced potatoes, ranch dressing, and 1 cup of the cheddar cheese. Toss to coat evenly.
Bake: Spread mixture into the dish. Cover with foil and bake 40 minutes or until potatoes are fork-tender.
Top and Finish: Remove foil, sprinkle remaining ½ cup cheese on top, and bake 10–15 minutes more until melty and golden.
Rest: Let stand 5–10 minutes before serving to thicken.

Servings

Serves 6–8 as a side dish.

Cook’s Notes

Works with frozen diced potatoes (hash brown style) — no thawing needed; just add 5–10 extra minutes.
For homemade ranch lovers, sub ¾ cup sour cream + ¼ cup ranch mix.
The potatoes should be roughly ½-inch dice for even cooking.
This casserole holds well on a buffet table for 1–2 hours.

Tips & Variations

Tips

Make ahead: Assemble up to 24 hours in advance and bake the day of.
Keep foil on during the first bake so potatoes steam and soften properly.
For crisp edges, broil the last 2–3 minutes.

Variations

Bacon Ranch: Add ½ cup cooked crumbled bacon.
Garlic Ranch: Stir in 1–2 minced garlic cloves.
Loaded Potato Style: Top with green onions, sour cream, and more cheese.
Spicy: Add diced jalapeños or ½ tsp cayenne.
Veggie Boost: Fold in 1 cup corn, peas, or chopped broccoli.

Q & A

Q: Can I use bottled ranch or homemade?

A: Freeze after baking and cooling. Reheat covered at 350°F for 25–30 minutes.

Q: How do I make it lighter?

A: Use light ranch dressing and reduced-fat cheese. You can also replace part of the dressing with Greek yogurt.

Q: What protein pairs well with this dish?
