Ingredients Notes
To make this recipe you will need the following ingredients:
- Pork tenderloin (fillets) – Lean and tender, perfect for slow cooking. Holds flavour well and stays juicy when cooked slowly in sauce.

- Stock – Provides moisture for slow cooking and helps create a rich, flavourful sauce.
- Paprika – Adds a subtle smokiness and colour to the sauce.
- Onion and garlic powder – Boost the overall flavour, reinforcing the fresh onion and garlic without adding extra moisture.

Variations and Substitutes
This dish is easy to tweak depending on what you have or what you’re in the mood for. Swap the pork for boneless skinless chicken thighs for a juicy, flavour-packed alternative, while chicken breasts aren’t the best choice as they are too lean and can make the sauce less rich.
You can also switch the honey for maple syrup or brown sugar for a different kind of sweetness, or leave out the thyme if you prefer a simpler, cleaner flavour.
You can adjust the heat by adding more or fewer red pepper flakes to suit your taste.
Changing up the sides each time, from rice and mashed potatoes to roasted vegetables or a crisp salad, gives the meal a fresh twist and keeps it feeling new every time you make it.
Tips for Slow Cooking Pork Tenderloin
Slow cooking pork tenderloin is simple, but a few tricks will help you get the most flavour and juiciness.
- Keep the fillets whole while cooking. This helps the pork stay juicy and prevents it from drying out. Slice only after cooking.
- Pat the meat dry before adding any sauce or seasoning. This ensures the flavours stick and the sauce isn’t watered down.
- Stick to the recommended cooking time: around 3 hours on high or 6 hours on low. If you need to keep it longer due to the timing of your meal, use a slow cooker with a keep warm function to prevent overcooking. This is especially useful if you’re busy with other dishes or entertaining.
- Layer flavours by adding spices and aromatics directly to the sauce rather than rubbing them on the meat. This ensures the pork absorbs maximum flavour as it cooks.
- Thicken the sauce at the end in a saucepan for the best results. Some slow cookers can handle adding cornstarch directly, but many don’t thicken well this way. If your slow cooker is reliable for thickening, you can stir in the cornstarch during the last hour of cooking, but using a saucepan is the safer option. While the sauce is thickening, let the pork rest before slicing.
- Slice and serve with the sauce once it is thickened.

Sides to Pair with Slow Cooker Honey Soy Balsamic Pork Tenderloin
This Slow Cooker Honey Soy Balsamic Pork Tenderloin pairs beautifully with a variety of sides, I love it with mashed potatoes and roasted carrots, but here are some other great options:
- Rice – fluffy and plain, or lightly seasoned like this Herby Garlic Seasoned Rice or Red Pepper Cilantro Rice to add extra flavour.
- Mashed potatoes – classic comfort food, I love this Lighter Mashed Potatoes.
- Roasted potatoes – golden and lightly seasoned.
- Sweet potato mash or Sweet Potato Fries – I love the flavour of sweet potato and this Sweet Potato Mash or Perfect Oven Baked Sweet Potato Fries are a great option.
- Butternut squash – roasted or mashed for a lighter alternative. Try these Paprika Roasted Butternut Squash
- Cauliflower – low-calorie, creamy and satisfying alternative to potatoes or rice. I love this Sour Cream and Onion Cauliflower Mash or Roasted Cauliflower Rice
- Vegetables – carrots, peas, asparagus, green beans, broccoli or a mix of your favourites, steamed or roasted.
Mix and match these sides to keep the meal feeling fresh each time you make it.

FAQ for Slow Cooker Honey Soy Balsamic Pork Tenderloin
Yes, boneless skinless chicken thighs work well as a substitute. Chicken breasts are not recommended because they are too lean and can make the sauce less rich.
Yes, cooked pork tenderloin in the sauce can be frozen. Store in an airtight container for up to 2–3 months. Thaw in the fridge overnight before reheating.
Reheat gently on the stove or in the microwave until warmed through. If the sauce has thickened too much, stir in a splash of stock, water, or a little soy sauce to loosen it.
