This Slow Cooker Onion and Potato Stew is a simple, comforting dish made with tender potatoes, sweet onions, garlic, and a flavorful broth.
The slow cooker allows the ingredients to cook gently for several hours, giving the onions time to soften and the potatoes to become tender. A little cornstarch at the end helps create a thicker, silky broth that turns this simple stew into a satisfying homemade meal.
It is an excellent choice for a cozy family dinner, especially on cool days when you want something warm without spending hours in the kitchen.

How to Make Slow Cooker Onion and Potato Stew
1. Prepare the Vegetables
Wash and peel the potatoes if desired, then cut them into approximately 1-inch cubes.
Thinly slice the onions into half-moon shapes and mince the garlic.
2. Add Everything to the Slow Cooker
Place the potatoes, sliced onions, and minced garlic into the slow cooker.
Pour in the broth and add the Worcestershire sauce, dried thyme, salt, and black pepper.
Stir gently so the ingredients are evenly distributed.
3. Slow Cook
Cover the slow cooker and cook on:
- LOW: 7–8 hours
- HIGH: approximately 4 hours
The stew is ready when the potatoes are tender enough to pierce easily with a fork and the onions are soft.
Cooking times can vary depending on the slow cooker and the size of the potato pieces.
4. Thicken the Stew
About 30 minutes before serving, combine the cornstarch with 2 tablespoons of cold water in a small bowl.
Whisk until completely smooth.
Stir the cornstarch mixture into the stew and continue cooking until the broth thickens.
Avoid adding dry cornstarch directly to the hot stew because it can create lumps.
5. Taste and Serve
Taste the stew and adjust the salt and black pepper if necessary.
Serve it hot with crusty bread, dinner rolls, or a simple green salad.
Helpful Tips
Choose the Right Potatoes
Yukon Gold potatoes work particularly well because they have a naturally creamy texture while generally holding their shape during slow cooking.
You can also use other firm potatoes if Yukon Golds aren’t available.
Add More Flavor to the Onions
For a deeper, richer flavor, sauté the sliced onions in a little butter or oil until golden before adding them to the slow cooker.
This extra step takes a little more time but can give the stew a more pronounced caramelized-onion flavor.
Cut the Potatoes Evenly
Try to cut the potatoes into similar-sized pieces so they cook at approximately the same rate.
Very large pieces may remain firm while smaller pieces become overly soft.
Optional Variations
Vegetarian Version
Use vegetable broth and check that the Worcestershire sauce you’re using is suitable for a vegetarian diet, or replace it with a vegetarian-friendly alternative.
Creamier Stew
For a richer texture, stir in a small amount of cream or milk near the end of cooking.
Add More Vegetables
You can add vegetables such as:
- Carrots
- Celery
- Mushrooms
- Peas
- Spinach
Add vegetables according to their cooking time so they maintain a pleasant texture.
Add Fresh Herbs
Fresh parsley or chives sprinkled over the finished stew can add a fresh flavor and a little color.
What to Serve With Potato Stew
This hearty stew pairs especially well with crusty bread.
Other options include:
- Garlic bread
- Dinner rolls
- Green salad
- Roasted vegetables
- Steamed green beans
The bread is especially useful for soaking up the flavorful broth.
Storage and Reheating
Allow leftovers to cool appropriately before transferring them to a covered container.
Store in the refrigerator and use within 3–4 days.
When reheating, warm the stew gently on the stovetop or in the microwave. If the broth becomes too thick after refrigeration, add a small amount of broth or water while reheating.
Frequently Asked Questions
Can I use regular potatoes instead of Yukon Gold?
Yes. Firm potatoes such as red potatoes can also work well. Keep the pieces similar in size so they cook evenly.
Can I make this stew without Worcestershire sauce?
Yes. You can leave it out or replace it with another savory seasoning according to your preference.
Why is my stew too thin?
Make sure the cornstarch is mixed with cold water before adding it. If the stew is still too thin after thickening, you can prepare a small additional cornstarch slurry and add it gradually.
Can I make it ahead?
Yes. This stew reheats well and can be prepared ahead for an easy meal later.
