Can I use frozen meatballs?
Yes. Use a 26 to 32 ounce bag of frozen meatballs. Warm them in the oven or slow cooker, then toss with the sauce until everything is hot and glossy. Homemade tastes best, but frozen is a totally valid party move.
What is chili sauce, exactly?
In this recipe, chili sauce means the jarred condiment (often near ketchup). It is smooth, tomato-based, tangy, and mildly spicy. It is not the same as hot sauce or chili crisp.
Can I make these in a slow cooker only?
You can, but I recommend baking first for better browning and less greasy sauce. If you want all-slow-cooker, shape the meatballs and arrange them in the slow cooker in a single layer if you can (avoid packing them in too tightly so they heat through safely). Cook on High for 2 to 3 hours or on Low for 4 to 5 hours, until the centers hit 160 to 165°F. Then add the sauce and cook 15 to 30 minutes more, stirring gently once or twice, until everything is hot and glossy. Skim excess fat if needed.
How do I keep meatballs warm for a party?
After baking and saucing, move them to a slow cooker on Warm (or Low if your Warm runs cool). They will hold well for about 2 to 3 hours. Stir occasionally so the sauce stays evenly coating everything, and add a splash of water if it thickens too much.
How many meatballs per person?
As an appetizer, plan on 4 to 6 meatballs per person if there are other snacks. If these are the main event, aim for 8 to 10.
