How to Make It

1. Preheat and Prep

Set your oven to 375°F (190°C) and grease a medium-sized baking dish. If your mashed potatoes are cold from the fridge, warm them slightly so they’re easier to spread.

2. Layer the Meatballs and Sauce

Add your cooked meatballs to the dish and pour marinara sauce all over them. You want them nestled in a saucy hug—every meatball should be coated.

3. Add the Mashed Potatoes

Spoon mashed potatoes over the meatballs and gently spread to cover everything. Don’t worry if it’s not perfectly smooth—those peaks will brown beautifully.

4. Cheese It Up

Sprinkle a mix of shredded mozzarella and parmesan over the potatoes. Dot with a few pats of butter for that irresistible golden top.

5. Bake to Perfection

Bake uncovered for 30–35 minutes, or until the cheese is bubbling and the top is golden. Let it rest for 5–10 minutes before digging in—this helps the layers settle.

Pro Tips for Success

Use a fork to rough up the potato topping for more crispy edges.
Warm the marinara before layering to cut down bake time.
Go heavy on the cheese if you love a super gooey top.
Add a splash of milk or cream to mashed potatoes if they seem dry.

Try a sprinkle of red pepper flakes or Italian seasoning on top

Reheat individual portions in the microwave or cover a dish with foil and warm in a 350°F oven. You can even turn leftovers into mini baked sliders—just scoop onto rolls and broil with cheese.

Yes, it freezes well! Assemble the bake (without baking), wrap tightly in foil and plastic wrap, and freeze up to 2 months. Thaw overnight in fridge and bake as directed.

Reheating

FAQs

Can you serve meatballs with mashed potatoes?
Oh yes, and it’s downright delicious. The creamy mashed potatoes soak up all that savory sauce from the meatballs—it’s like a hug on a plate. This bake takes that classic combo and makes it even better.

Is it better to bake meatballs at 350 or 400?
Both work, but I like 400°F for a slightly quicker bake and a bit more browning on the outside. You’ll get that lovely caramelization without drying them out—just keep an eye on them around the 18-minute mark.

What does Gordon Ramsay put in his mashed potatoes?
Chef Ramsay is all about velvety, indulgent mashed potatoes. He adds butter (lots), warm cream or milk, and sometimes even crème fraîche for tang. And of course, seasoning is key—salt and a touch of white pepper.

Can you use instant mashed potatoes instead of breadcrumbs for meatballs?
Surprisingly, yes! Instant mashed potato flakes can help bind meatballs and keep them moist. They’re a great gluten-free swap and add a creamy texture inside—just go easy on the quantity so the mix doesn’t get too soft.
