Mom's Creamy Baked Mashed Potatoes

Rich, creamy mashed potatoes baked to perfection with cream cheese, Parmesan, butter, and sour cream.

Everyone loved these creamy baked mashed potatoes. My mom often doubled the recipe, so there would be enough for another meal later in the week. No one ever complained about having these leftovers! In fact, many of us thought they tasted even better the next day after the flavors had blended together.

Cream cheese, sour cream, butter, and Parmesan cheese make these mashed potatoes extra rich and creamy, making them perfect for holiday dinners, Sunday suppers, or any family gathering.

Ingredients:

5 potatoes, peeled and quartered
4 oz. cream cheese, softened
1/2 c. sour cream
1/4 c. milk (or more)
4 Tbs. butter, divided
1/4 to 1/2 c. grated Parmesan cheese
2 tsp. dried parsley flakes
1 tsp.  garlic powder
3/4 tsp. onion powder
1/4 tsp. paprika
Salt and pepper to taste

Directions:

Preheat the oven to 350°F. Butter a 2-quart baking dish with a lid.

Place the potatoes in a large saucepan and add enough cold water to cover them by about 1 inch. Bring to a boil over high heat.

Reduce the heat to medium and cook for 15 to 20 minutes, or until the potatoes are fork-tender. Drain well.

Return the potatoes to the warm saucepan. Mash with a potato masher or beat with an electric mixer until mostly smooth.

Add the cream cheese, sour cream, milk, 2 tablespoons butter, Parmesan cheese, parsley flakes, and garlic powder. Beat until smooth and creamy.

Season with salt and pepper to taste. If the potatoes are thicker than you'd like, add a little more milk, about 1 tablespoon at a time, until they reach your desired consistency.

Spoon the mashed potatoes into the prepared baking dish. Smooth the top, building the edges slightly higher than the center to help keep the melted butter from running over the sides.

Dot the top with the remaining 2 tablespoons butter and sprinkle with paprika.

Cover with the lid and bake for 30 to 40 minutes, or until heated through.

Remove from the oven and gently stir the potatoes to distribute the melted butter evenly throughout. Garnish with a little extra parsley, if desired, and serve hot.

Mom's Tip: My mom always baked these mashed potatoes covered, then gave them a good stir before serving, so the melted butter was mixed throughout the potatoes. That way, everyone enjoyed the rich buttery flavor in every spoonful.

Tips for Best Success:

• Use starchy potatoes like Russet or Yukon Gold for the creamiest texture.
• Start with cold water when boiling the potatoes so they cook evenly.
• Drain the potatoes well to prevent watery mashed potatoes.
• Return the drained potatoes to the warm pan for 1 to 2 minutes to evaporate excess moisture before mashing.
• Soften the cream cheese before mixing it into the potatoes for a smoother texture.
• Warm the milk slightly so it blends into the potatoes more easily.
• Bake covered to keep the potatoes moist and creamy.
• Stir before serving to evenly distribute the melted butter throughout the casserole.

Variations and Substitutions:

• Use light sour cream, reduced-fat cream cheese, and milk instead of whole milk.
• Freshly grated Parmesan melts more smoothly than pre-shredded varieties.
