Ingredients
For about 4–6 servings:
- 8 sausages
- 2 large onions, thinly sliced
- 2 cups beef stock
- 1 teaspoon minced garlic
- 2 teaspoons Worcestershire sauce
- 3 tablespoons cornstarch
- 4 tablespoons cold water
- ½ teaspoon black pepper
- ½ teaspoon dried mixed herbs, optional
- 1 tablespoon cooking oil
You can use beef, pork, Italian-style, or other sausages depending on what you enjoy. Different versions of this dish work with a variety of sausage types.
How to Make Slow Cooker Sausages with Onion Gravy
1. Brown the Sausages
Heat a little oil in a large frying pan over medium-high heat.
Add the sausages and brown them on the outside for a few minutes, turning occasionally.
You don’t need to cook them completely at this stage. Browning simply adds extra flavor and color. Some versions of the recipe skip this step entirely, so it’s optional if you’re short on time.
2. Add the Onions
Place the sliced onions in the bottom of your slow cooker.
Arrange the browned sausages over the onions.
As everything cooks, the onions soften and absorb the savory flavors from the sausages and cooking liquid.
3. Make the Cooking Liquid
In a bowl or measuring jug, combine:
- Beef stock
- Minced garlic
- Worcestershire sauce
- Black pepper
- Optional dried herbs
Pour the mixture over the sausages and onions.
4. Slow Cook
Cover the slow cooker and cook on LOW for approximately 5–6 hours, or until the sausages are thoroughly cooked and tender.
Cooking times can vary depending on your slow cooker and the type and size of sausages. Similar recipes use roughly 4–6 hours on low.
5. Thicken the Onion Gravy
When the sausages are cooked, carefully remove them from the slow cooker.
Mix the cornstarch with cold water until completely smooth.
Stir the slurry into the hot cooking liquid.
Return the sausages to the slow cooker and cook on HIGH for about 20–30 minutes, or until the gravy becomes thick and glossy. This cornstarch-slurry method is commonly used in slow-cooker versions of sausage and onion gravy.
Taste the gravy and adjust the seasoning if needed.
What to Serve With It
The classic choice is creamy mashed potatoes. Spoon plenty of onion gravy over the sausages and potatoes for a wonderfully comforting dinner.
You can also serve them with:
- Steamed peas
- Green beans
- Roasted carrots
- Broccoli
- Mashed sweet potatoes
- Crusty bread
- Rice
- Egg noodles
A side of vegetables adds color and freshness to the rich gravy.
Tips for the Best Sausages and Gravy
Don’t Overcrowd the Slow Cooker
Arrange the sausages so they’re sitting reasonably evenly over the onions. This helps the heat circulate properly.
Slice the Onions Thinly
Thinly sliced onions soften more easily and become almost melt-in-your-mouth tender during slow cooking.
Don’t Add Too Much Salt
Stock, sausages, and Worcestershire sauce can already contain quite a bit of sodium. Taste the finished gravy before adding additional salt.
Make the Gravy Extra Rich
For deeper flavor, brown the sausages before adding them to the slow cooker. You can also lightly sauté the onions in the same pan before transferring them to the cooker.
Can You Add Mushrooms?
Absolutely.
Sliced mushrooms make an excellent addition. Add them along with the onions before cooking.
You can also add peas, carrots, or green beans toward the end of cooking for a more complete one-pot meal. Some sausage-and-onion slow-cooker recipes specifically recommend mushrooms and vegetables as variations.
Can You Freeze It?
Sausages with onion gravy can be suitable for freezing once cooled properly. Allow the cooked meal to cool, portion it into airtight freezer-safe containers, and refrigerate or freeze promptly.
Thaw safely in the refrigerator and reheat thoroughly before serving.
If you’re freezing leftovers, mashed potatoes can be stored separately for the best texture.
