Slow Cooker Sausages with Caramelized Onion Gravy

Description

These Slow Cooker Sausages with Caramelized Onion Gravy are the ultimate cozy comfort dinner. Juicy, golden-browned sausages cook slowly with tender onions in a rich, savory gravy until every bite is packed with flavor. Browning the sausages first gives them a beautiful caramelized exterior, while slow cooking allows the onions to become wonderfully soft and sweet. The gravy develops right in the crockpot, soaking up all those delicious sausage juices. Serve this easy slow cooker meal over creamy mashed potatoes with green beans or peas for a satisfying family dinner that requires very little hands-on preparation.

Ingredients For the Sausages

• 8 thick pork or beef sausages
• 1 tbsp olive oil
• ½ tsp freshly ground black pepper
• ½ tsp garlic powder

For the Onion Gravy

• 3 large yellow onions, thinly sliced
• 3 garlic cloves, minced
• 2 tbsp unsalted butter
• 2 cups low-sodium beef broth
• 1 tbsp Worcestershire sauce
• 1 tbsp Dijon mustard
• 1 tsp dried thyme
• ½ tsp dried rosemary
• ½ tsp smoked paprika
• ½ tsp freshly ground black pepper
• Salt, to taste

For Thickening

• 2 tbsp cornstarch
• 3 tbsp cold water

For Serving

• Creamy mashed potatoes
• Steamed green beans or peas
• Fresh parsley, chopped
• Freshly ground black pepper

Step-by-Step Instructions

1. Heat the olive oil in a large skillet over medium-high heat.
2. Add the sausages in a single layer, leaving enough room between them to brown properly.
3. Cook for approximately 2–3 minutes per side, turning until the outside is deeply golden. The sausages do not need to be completely cooked at this stage.
4. Transfer the browned sausages to a plate.
5. Reduce the skillet heat to medium and add the butter.
6. Add the sliced onions and cook for approximately 6–8 minutes, stirring occasionally, until softened and beginning to caramelize.
7. Add the minced garlic and cook for another 30 seconds until fragrant.
8. Transfer the onion and garlic mixture to the bottom of a 5–6 quart slow cooker.
9. Arrange the browned sausages over the onions.
10. In a medium bowl, combine beef broth, Worcestershire sauce, Dijon mustard, thyme, rosemary, smoked paprika, and black pepper.
11. Whisk until thoroughly combined.
12. Pour the broth mixture over the sausages and onions.
13. Gently move the sausages so some of the liquid reaches underneath them.
14. Cover the slow cooker with the lid.
15. Cook on LOW for approximately 5–6 hours or HIGH for approximately 2½–3½ hours, until the sausages are thoroughly cooked.
16. Cooking time may vary depending on the thickness and type of sausage used.
17. Check doneness with an instant-read thermometer according to the safe internal temperature for the meat in your sausages.
18. Once cooked, carefully transfer the sausages to a clean plate and cover loosely to keep warm.
19. In a small bowl, whisk together the cornstarch and cold water until completely smooth.
20. Pour the cornstarch slurry into the onion gravy.
21. Stir thoroughly.
22. Cover and cook on HIGH for another 10–15 minutes, or until the gravy has thickened.
23. Taste the gravy and adjust the salt and black pepper as needed.
24. Return the sausages to the crockpot.
25. Gently spoon the hot caramelized onion gravy over each sausage.
26. Allow everything to warm together for another few minutes.
27. Sprinkle with freshly chopped parsley.
28. Serve the sausages hot with plenty of caramelized onions and gravy spooned over the top.

Tips

• Brown the sausages first. This extra step creates a much richer flavor and gives them the beautiful browned appearance shown in the finished dish.
• Use thick, good-quality sausages because they hold their shape better during slow cooking.
• Don’t overcrowd the skillet when browning. Work in batches if necessary.
• Slice the onions evenly so they soften at approximately the same rate.
• For a darker, richer gravy, let the onions caramelize a little longer before transferring them to the crockpot.
• Always mix cornstarch with cold water before adding it to hot gravy to prevent lumps.
• If the gravy becomes too thick, stir in a splash of beef broth.
• If it’s too thin, add a little more cornstarch slurry and cook until thickened.

Notes

This recipe is especially good served over buttery mashed potatoes because they soak up the rich onion gravy. Rice, egg noodles, roasted potatoes, or crusty bread also work beautifully. For additional vegetables, serve with steamed peas, broccoli, carrots, or green beans. Refrigerate leftovers promptly in an airtight container for up to 3–4 days and reheat thoroughly before serving.

Q&A

Can I put raw sausages directly into the slow cooker?
You can, provided they’re cooked to a safe internal temperature before serving, but browning them first gives the finished dish much better color and flavor.
Which sausages work best?
Pork, beef, chicken, turkey, bratwurst, or other fresh thick sausages can work. Cooking times and safe internal temperatures can vary depending on the meat.
Can I add potatoes directly to the crockpot?
Yes. Small baby potatoes or chopped potatoes can be added underneath the sausages for an easy one-pot meal.
Can I make the gravy without cornstarch?
Yes. You can leave it thinner or use another suitable thickener. Cornstarch simply creates a glossy, thicker gravy.
Can I add mushrooms?
Absolutely. Sliced mushrooms pair especially well with sausages and onion gravy. Add them with the onions.
What should I serve with slow cooker sausages?
Mashed potatoes are a classic choice, but rice, noodles, roasted vegetables, peas, green beans, or crusty bread are also delicious.
