- 1/2 cup milk: Adjustable to achieve your perfect creaminess; warm it slightly for easier mixing.

- 1 teaspoon onion powder: Complements the garlic with a subtle sweetness and depth.
- Salt and freshly ground black pepper: Essential for seasoning and bringing out all the flavors.

How to Make Creamiest Baked Mashed Potatoes Recipe
Step 1: Preheat Your Oven
Set your oven to 350 degrees Fahrenheit (175 degrees Celsius) to get it ready for baking. This ensures the mashed potatoes will bake evenly and develop that golden top we all love.
Step 2: Cook the Potatoes
Bring a large pot of salted water to a boil, then add your peeled and cubed russet potatoes. Cook them for around 15 to 20 minutes until fork-tender—this is key for achieving creamy, smooth mashed potatoes.
Step 3: Drain and Cool
Drain all the water thoroughly from the potatoes and return them to the pot. Let them cool just enough to handle but not long enough to lose warmth, as warm potatoes mash better and soak up moisture.
Step 4: Mash Until Creamy
Using a potato masher or an electric mixer, mash those potatoes until you get a wonderfully smooth and creamy texture with no lumps. This is the foundation of your recipe’s luscious texture.
Step 5: Mix in Butter, Sour Cream, and Milk
Stir in the softened butter, sour cream, and milk. Mix everything well until you achieve the ultimate creaminess. If the potatoes feel too thick, add a splash more milk gradually to loosen them up just right.
Step 6: Season to Perfection
Add your garlic powder, onion powder, salt, and pepper to taste. Stir well so every bite is packed with balanced, savory flavors that enhance the potatoes without overpowering.
Step 7: Add Cheddar Cheese
This step is optional but highly recommended! Fold in shredded cheddar cheese for more richness inside the mash and a beautiful melty effect when baked.
Step 8: Transfer to Baking Dish
Grease a 9×13-inch baking dish and spread your creamy mashed potato mixture evenly with a spatula. This gives you space for that gorgeous golden top to form while baking.
Step 9: Bake Until Golden
Bake the potatoes in your preheated oven for 25 to 30 minutes or until the top looks bubbly and golden brown—this gives a perfect contrast between creamy inside and slightly crisp outside.
Step 10: Cool Slightly and Garnish
Once baked, remove the dish from the oven and let it cool for a few minutes before serving. Top with fresh chopped chives or green onions for a pop of color and fresh flavor.

Reheating
Reheat leftovers gently in the oven at 350 degrees Fahrenheit until warm throughout. Cover with foil to retain moisture or microwave with a damp paper towel to keep the potatoes creamy and prevent drying out.
FAQs
Can I use a different type of potato for this recipe?
While russet potatoes are best for their starchy texture and fluffiness, you can use Yukon Golds for a slightly creamier and buttery flavor. Just keep in mind it may alter the final texture slightly.
Is sour cream necessary, or can I substitute it?
Sour cream adds tang and creaminess that really enhances this recipe. You can substitute with Greek yogurt for a similar effect or cream cheese for extra richness, but the texture and flavor will vary a bit.
Can I make this recipe dairy-free?
Absolutely! Use dairy-free butter and swap sour cream and milk for your favorite plant-based alternatives like coconut cream or almond milk to keep it creamy and delicious without dairy.
How can I make this recipe ahead of time for a party?
You can prepare everything through step 8, cover the baking dish, and refrigerate it. Then bake just before serving to have fresh, warm potatoes perfect for your gathering.
Why is baking the mashed potatoes important?
Baking adds a delightful texture contrast with a golden, bubbly crust, which elevates this dish beyond traditional mashed potatoes. It also helps develop deeper flavors and warmth that’s so comforting.
