You want 400°F (200°C). Not 350°, not 450°. Four-hundred. This is the Goldilocks zone of frozen meatball roasting. Too low, and they sweat; too high, and you get a charcoal hockey puck.
Pop them in for about 18-22 minutes. But here’s the kicker: shake the pan halfway through. Just give it a good rattle like you’re playing a maraca made of meat. This ensures even browning on all sides.
When are they done? They should look like little, glorious brown planets. A little darker on the bottom is okay—that’s the good part. That’s texture.
The Saucing Strategy (Don’t Mess This Up)
Do not—I repeat, do not—pour sauce on them before they go in the oven. That’s how you get steamed meatballs. Sad, pale meatballs. We’re not here for that. We’re here for crust.
Roast them naked first. Let them get that gorgeous brown shell. Then you toss them in your sauce. Barbecue, marinara, sweet chili, whatever. Toss them in a bowl right when they come out of the oven.
If you want to go full fancy? Put the sauced meatballs back in the oven for five more minutes. The sauce caramelizes and sticks to the meatball like a tasty sweater. It’s a game-changer, trust me.
