Step-by-Step Guide to Making Baked Mashed Potatoes
Step 1 – Choose and Prep the Potatoes
Select starchy potatoes like Russet or Yukon Gold for the creamiest texture. Peel them if desired, then cut into evenly sized chunks. Rinse briefly under cold water to remove excess starch.
Step 2 – Boil Until Fork-Tender
Place the potato chunks in a large pot and cover with cold, salted water. Bring to a boil, then reduce to a gentle simmer. Cook for 15–20 minutes, or until the potatoes are fork-tender and easily pierced.
Step 3 – Drain and Dry
Drain the potatoes thoroughly in a colander. Return them to the warm pot and let them sit for a few minutes to allow excess moisture to evaporate. This step prevents watery mashed potatoes.
Step 4 – Mash to Perfection
Mash the potatoes using a potato masher or ricer until smooth. Avoid overmixing, as this can make them gummy. Aim for a fluffy consistency.
Step 5 – Add Creamy Ingredients
Stir in softened butter, warm milk or heavy cream, salt, and black pepper. For extra richness, add sour cream or cream cheese. Mix gently until creamy and well combined.
Step 6 – Transfer to Baking Dish
Preheat your oven to 375°F (190°C). Spoon the mashed potatoes into a lightly greased baking dish. Smooth the top with a spatula.
Step 7 – Add Toppings
Sprinkle shredded cheese, grated Parmesan, or breadcrumbs over the top. You can also add chopped chives, bacon bits, or a drizzle of melted butter for added flavor.
Step 8 – Bake Until Golden
Bake for 20–25 minutes, or until the top is heated through and lightly golden. For extra browning, broil for the last 2–3 minutes. Let cool slightly before serving.

FAQs about Baked Mashed Potatoes Recipe
1. Can I make baked mashed potatoes without eggs?
Yes, you can. Eggs help add structure and a slightly firmer texture when baking, but they are completely optional. The recipe will still turn out creamy and delicious without them.
2. Can I use milk instead of heavy cream?
Absolutely. Whole milk works very well as a substitute for heavy cream. If you want to maintain richness, simply add a little extra butter to compensate for the lower fat content.
3. Why are my mashed potatoes gluey?
Mashed potatoes become gluey when they are overmixed or processed in a blender or food processor. Potatoes release starch when overworked, creating a sticky texture. Mash gently by hand or use a ricer for the best results.
4. Can I add cream cheese?
Yes, cream cheese is a great addition. It adds tanginess and extra richness to the mashed potatoes. You can replace part of the sour cream or butter with softened cream cheese for a smoother flavor.
5. How do I make the top extra crispy?
For a golden, crispy top, switch the oven to broil for the last 2–3 minutes of baking. Watch closely to prevent burning and ensure even browning.
