Here’s a simple and delicious way to make slow cooker sausages with onion gravy. This method gives you tender sausages and a rich, flavorful gravy without standing over the stove.
Ingredients (Serves 4)
- 8–10 sausages (pork, beef, or your choice)
- 2 large onions, thinly sliced
- 2 cloves garlic, minced (optional)
- 2 tbsp olive oil or butter
- 2 cups beef or vegetable stock
- 1 tbsp Worcestershire sauce
- 1 tsp dried thyme (or 1 tbsp fresh)
- 2 tbsp plain flour (for thickening)
- Salt and pepper, to taste
- Optional: 1 tsp mustard for extra flavor
Instructions
- Prep the sausages
- Brown sausages in a skillet with a little oil over medium heat until golden on all sides (about 5–7 minutes).
- Transfer them to the slow cooker. Browning adds flavor but isn’t strictly necessary.
- Cook the onions
- In the same skillet, add butter or oil.
- Sauté the sliced onions (and garlic if using) until soft and lightly caramelized, about 8–10 minutes.
- Transfer onions to the slow cooker over the sausages.
- Add liquids and seasoning
- Pour in the stock and Worcestershire sauce.
- Add thyme, salt, and pepper. Stir gently.
- Slow cook
- Cover and cook on low for 6–7 hours or high for 3–4 hours.
- Sausages should be cooked through and tender, and onions should be soft and sweet.
- Make the gravy
- About 20 minutes before serving, mix the flour with a little cold water to make a smooth paste (slurry).
- Stir the slurry into the slow cooker to thicken the gravy.
- Cook on high for the remaining time until the gravy reaches your desired consistency.
- Taste and adjust seasoning.
- Serve
- Serve sausages with plenty of onion gravy on mashed potatoes, rice, or buttered bread.
💡 Tips for best results
- For extra depth, add a splash of red wine or balsamic vinegar to the gravy.
- Use a mix of sausages (herby, spicy) for more flavor.
- You can also add sliced mushrooms with the onions for a richer gravy.
If you want, I can give you a shortcut 1-step version that doesn’t even require browning the sausages and still makes a rich onion gravy. Do you want me to do that?
