🛒 Ingredients You’ll Need
- 3 pounds Yukon gold potatoes – peeled and chopped

👩🍳 Step-by-Step: How to Make Cheesy Baked Mashed Potatoes
1. Get Things Hot & Ready
Preheat your oven to 400°F and grease a 2-quart baking dish. Butter, cooking spray—whatever floats your casserole.
2. Boil Those Spuds
Chop your Yukon golds into even chunks and boil them until fork-tender (about 10 minutes). Drain and cool just a bit.
3. Melt the Magic
While potatoes are boiling, warm milk, butter, salt, and pepper in a saucepan. Stir in sour cream once melted. No simmering needed—just a cozy, creamy blend.
4. Mash Like You Mean It
Mash those taters until mostly smooth (or a few lumps if that’s your thing). Pour in the warm mixture and fold in cheddar cheese. Taste and adjust seasoning as needed.
5. Assemble and Bake
Spread into your dish, top with Parmesan, and bake for 20 minutes. Then broil for 2–3 minutes until that top is golden and glorious.
6. Garnish & Serve
Optional—but highly recommended: sprinkle with chopped chives or parsley for a fresh pop of green.
🧠 Tips From Hanna’s (me) Kitchen
- Make Ahead Like a Pro: Prep the entire dish a day early. Just pop it in the oven before dinner.
- Cheese Swap Alert: Gouda or Monterey Jack are delicious backups if you’re out of cheddar.
- Crust Lovers Unite: Want a crispier top? Add an extra sprinkle of Parmesan before broiling.
And hey, if your mashed potatoes aren’t perfectly smooth—don’t sweat it. That rustic charm is part of what makes homemade so lovable!
