These Slow Cooker Balsamic Garlic Mushrooms are tender, juicy, and coated in a rich, glossy balsamic garlic sauce. An easy side dish perfect for dinner, holidays, or meal prep!
Introduction
Honestly, mushrooms are one of those ingredients that can go from simple to absolutely delicious with just a few good flavors. I usually make these Slow Cooker Balsamic Garlic Mushrooms when I want an easy side dish that doesn’t require much hands-on cooking.
The slow cooker does most of the work here. The mushrooms slowly soak up a sweet, tangy, garlicky sauce until they become incredibly tender and glossy. And that little sprinkle of flaky salt at the end? It makes the whole dish even better.
I love serving these alongside steak, roasted chicken, mashed potatoes, or even crusty bread for soaking up all that extra sauce.
Ingredients
- 1½ lbs (680 g) whole button or cremini mushrooms, cleaned
- â…“ cup balsamic vinegar
- ¼ cup low-sodium soy sauce
- 3 tbsp olive oil
- 2 tbsp honey or brown sugar
- 4 cloves garlic, minced
- 1 tsp Italian seasoning
- ½ tsp black pepper
- ½ tsp onion powder
- ¼ tsp red pepper flakes, optional
- 2 tbsp butter
- 1 tbsp fresh parsley, chopped
- Flaky salt, for finishing
- 1 tsp cornstarch + 1 tbsp water, optional for a thicker sauce
Step-by-Step Method
1. Clean the mushrooms
Gently wipe the mushrooms clean with a damp paper towel. If they are large, you can cut them in half, but small mushrooms can be left whole.
2. Make the sauce
In a bowl, whisk together the balsamic vinegar, soy sauce, olive oil, honey or brown sugar, minced garlic, Italian seasoning, black pepper, onion powder, and red pepper flakes.
3. Add everything to the slow cooker
Place the mushrooms into the slow cooker and pour the balsamic garlic mixture over them. Add the butter on top.
Give everything a quick toss so the mushrooms are evenly coated.
4. Slow cook
Cover and cook on LOW for 3–4 hours or HIGH for 1½–2½ hours, depending on the size of your mushrooms.
I usually prefer LOW because the mushrooms have more time to absorb all those delicious flavors.
5. Thicken the sauce if desired
If you want a thicker, glossy sauce, mix the cornstarch with water to make a slurry. Stir it into the mushrooms during the final 15–20 minutes of cooking.
6. Finish and serve
Taste and adjust the seasoning if needed. Sprinkle with fresh parsley and a little flaky salt before serving.
The mushrooms should be tender, juicy, and beautifully coated in that rich balsamic glaze.
Cooking Tips
- Don’t overcrowd the slow cooker. Mushrooms release quite a bit of liquid as they cook.
- Use whole mushrooms for the best texture and presentation.
- For a sweeter glaze, add another teaspoon of honey or brown sugar.
- For extra garlic flavor, add one additional minced clove near the end.
- A pinch of red pepper flakes gives the mushrooms a subtle spicy kick.
- If the sauce seems too thin, use the cornstarch slurry or leave the lid slightly ajar for the final 20–30 minutes.
- Don’t overcook them, or the mushrooms can become too soft.
Serving Suggestions
These mushrooms are incredibly versatile. I usually serve them as a side dish with:
- Grilled or roasted steak
- Roast chicken
- Pork chops
- Mashed potatoes
- Rice or quinoa
- Pasta
- Crusty garlic bread
- Burgers or sandwiches
They also make a fantastic addition to a holiday dinner table.
