About the Ingredients
Smoked kielbasa — I usually buy whatever’s on sale, honestly. I’ve used the Polish-style rope sausage, I’ve used the hillshire farm dinner sausage in the curve, I’ve used turkey kielbasa when I was briefly trying to be better about that sort of thing. It all works. The turkey version is a little leaner and doesn’t get quite as rich in the sauce, but it’s still good. I slice them about a half-inch thick, sometimes a little thicker if I’m not paying close attention.
The grape jelly. I know. I know. It sounds so wrong. But please don’t substitute strawberry or raspberry — I tried once and it was fine but it wasn’t right. There’s something specific about grape that works here, that tartness against the smoke, and I honestly don’t know enough about food science to explain it but I’ve just accepted it. Concord grape. Regular old Welch’s or the store brand. Two cups.
Barbecue sauce. This is where you can have some opinions. I usually use a hickory-smoked variety because I like the depth it adds, but I’ve used honey barbecue, I’ve used spicy barbecue, I’ve even used whatever sad half-bottle was left in the door of the fridge and it was fine. Use what you like. Two cups.
Ingredients
3 pounds smoked kielbasa, sliced into roughly ½-inch rounds (I’m not precise about it)
2 cups grape jelly — Concord grape, please
2 cups barbecue sauce, your choice, hickory if you have it
How to Make It
You really can do this in five minutes if you move with any kind of purpose, which I usually don’t because I’m also trying to find my keys or figure out what I did with the lid to the Slow Cooker.
Slice the kielbasa. Just go down the rope making rounds, not too thin or they’ll kind of disappear in the sauce, not too thick or they’ll take longer to heat through. Dump them into the bottom of the Slow Cooker — I use a six-quart one, though I’ve crammed this into a four-quart in a pinch.
Spoon the grape jelly over the top. All of it, spread around a bit. Then pour the barbecue sauce over that. Don’t stir it yet. I made the mistake of stirring it right at the beginning once and something about it wasn’t quite right — I can’t explain why, and maybe it doesn’t matter, but now I just leave it alone and let everything sort of melt together on its own terms.
Lid on. Low for three to four hours, or high for about an hour and a half to two hours if you’re in a hurry. You’ll know it’s ready when the jelly’s completely dissolved and the sauce looks smooth and glossy and the kielbasa is heated all the way through.
Then stir it. Really give it a good stir at this point — you want every piece coated. Switch to warm, set out toothpicks, and that’s genuinely it. I usually give it a stir every so often just to keep the sauce from settling, but you don’t have to
Variations
A fun version uses half kielbasa and half frozen meatballs — just fully cooked frozen ones, dropped in right at the start — and it’s actually really good for a bigger crowd. Stretches it further. I tried doing it with cocktail weenies once, back when the kids were little, and it was fine, sweet and familiar, though I like the meatier bite of the kielbasa better now.
If you want some heat, a spicy barbecue sauce does the trick, or you can stir in some red pepper flakes after it’s done. I’ve also added a splash of apple cider vinegar at the end when I thought the sauce was getting too sweet, and that helped cut through it.
One time someone suggested adding pineapple chunks in the last hour. A can, drained. I was skeptical but honestly it was pretty good. More of a luau feel, but in a good way.
Leftovers
These keep in the fridge for three or four days. Maybe five if I’m being optimistic, which I usually am with leftovers and usually regret. The sauce gets thick when it cools, almost jammy, so when you reheat it just add a small splash of water and stir it around and it loosens right back up. Microwave works fine. Stovetop if you want to do it properly.
The leftovers are honestly how I discovered these are good over egg noodles. I had maybe a cup and a half left one evening and didn’t want to figure out dinner and I just tossed them over buttered egg noodles and it was — okay this sounds like I’m overselling it, but it was legitimately good. Rich and comforting in that slightly embarrassing way where you don’t want to admit how much you liked it.
