These low carb 3-ingredient kielbasa Stratford bites are the kind of easy party food that disappears fast, and it is easy to see why. With smoky kielbasa, tangy mustard, and plenty of melted mozzarella, they bake up into warm, savory little bites that feel retro in the best possible way. This recipe has that church-basement, card-table, passed-around-on-an-index-card charm, and it is still just as handy today for game nights, holiday snacks, and simple family gatherings.

Serve these bites warm on a platter with toothpicks alongside crisp celery, sliced cucumbers, or a simple green salad if you want to keep the meal low carb. They also fit right in on an appetizer spread with deviled eggs, pickle spears, olives, and sparkling water, beer, or iced tea. If you are feeding a crowd, a bowl of roasted vegetables on the side rounds things out nicely.

Ingredients

1 pound kielbasa sausage, sliced into 1/2-inch rounds

1/2 cup yellow mustard
2 cups shredded mozzarella cheese

Directions

1. Preheat the oven to 375°F and lightly grease a baking dish or small sheet pan.

2. Spread the kielbasa slices in a single layer in the prepared baking dish.

3. Spoon or drizzle the yellow mustard evenly over the kielbasa slices, coating the tops lightly.

4. Sprinkle the mozzarella cheese over everything, making sure each slice gets a good layer.

5. Bake for 15 to 20 minutes, until the cheese is melted and bubbling and the edges of the kielbasa are browned. Serve hot.

Variations & Tips

For a sharper flavor: Swap part of the mozzarella for sharp cheddar or provolone. You will get a stronger cheesy bite that works especially well for adults who like bolder snack trays.

For picky eaters: Use a milder smoked sausage and go light on the mustard the first time. You can always serve extra mustard on the side for the folks who want more tang.

Make-ahead tip: Slice the kielbasa and assemble the dish a few hours ahead, then cover and refrigerate. When guests arrive, just bake until hot and bubbly.

Easy serving tip: If you are putting these out for a party, keep them warm in a small slow cooker or warming tray so the cheese stays soft and stretchy longer.
