This 5-ingredient slow cooker kipper snacks recipe is the kind of budget-friendly, pantry-based meal that comes together with almost no effort, which is exactly why it earns a spot in a busy weeknight rotation. Using the undrained tin adds instant flavor and moisture right to the crock pot, and with just a few simple add-ins, the fish turns into a warm, savory dish that feels surprisingly hearty. It has a practical old-school charm to it, like the kind of simple meal you throw together on a long day and end up making again because it worked so well.
Serve this over hot rice, buttered noodles, mashed potatoes, or thick slices of toast to soak up the flavorful juices. A crisp side salad, steamed green beans, peas, or roasted carrots help balance the richness, and if you want to keep things especially cozy, a scoop alongside baked potatoes makes it feel like a complete comfort-food dinner.
5-Ingredient Slow Cooker Kipper Snacks
Servings: 2 to 3
Ingredients
1 undrained tin kipper snacks
1 medium onion, thinly sliced
1 cup canned diced tomatoes, with juices
2 tablespoons brown mustard
1 tablespoon Worcestershire sauce
Directions
1. Lightly grease the inside of the slow cooker if desired for easier cleanup, then add the undrained tin of kipper snacks to the bottom of the crock.
2. Scatter the sliced onion over the fish, then spoon the diced tomatoes and their juices on top.
3. Drizzle in the brown mustard and Worcestershire sauce, spreading them as evenly as you can over the top.
4. Cover and cook on Low for 1 1/2 to 2 hours, just until everything is hot and the onions have softened. Avoid overcooking so the fish keeps its texture.
5. Gently spoon the kipper mixture onto plates or into shallow bowls and serve hot with rice, toast, mashed potatoes, or noodles.
Variations & Tips
Add a little sweetness: If you like the classic sweet-savory balance that works so well with smoky fish, stir in 1 to 2 teaspoons of brown sugar before cooking. It softens the tang of the mustard and tomatoes nicely.
Make it heartier: Add sliced potatoes or drained white beans to the slow cooker to stretch the meal a bit further. If using potatoes, slice them thinly and expect a longer cooking time so they become tender.
Keep the fish intact: Kipper snacks can be delicate, so avoid stirring too much once everything is in the slow cooker. A gentle spoon under the fillets at serving time helps keep larger pieces together.
Prep-ahead tip: Slice the onion and measure the sauces the night before so all you have to do in the morning is layer everything into the crock pot. It is a nice shortcut on especially busy weekdays.
