Essential Ingredient Guide
- 16 oz cremini or button mushrooms: I always suggest giving these a gentle wipe with a damp cloth. You want them clean, but not soaked, so they roast up golden rather than steaming in the pan.
- 4 large russet potatoes: Russets are just wonderful for that fluffy, cloud-like texture. Just make sure you peel and cube them evenly so they all soften at the exact same time.
- 1 tsp fresh chives: These are optional, but oh, they add such a delicate, oniony brightness. It's a small touch, but it really makes the 1 cup chopped kale pop.
- 1 tsp fresh thyme leaves: Thyme has this earthy, woody scent that reminds me of the garden. It blends so beautifully with the mushrooms while they're roasting.
- 2 tbsp balsamic vinegar: This is the secret to that deep, tangy glaze. It transforms the mushrooms from simple to something a bit more sophisticated, honestly.
- 2 tbsp unsalted butter: I use unsalted so I can control the seasoning myself. It gives the mash that creamy, velvety finish we all crave.
Complete Cooking Process
-
Getting Everything Ready:
Start by getting your 4 large russet potatoes peeled and cubed and your 16 oz cremini or button mushrooms sliced. Having your 1 cup chopped kale and minced garlic ready to go makes the whole process feel so much calmer.
-
Building the Flavor:
The magic happens when you whisk together the 2 tbsp balsamic vinegar, 2 tbsp olive oil, and 1 tsp Dijon mustard. Tossing the mushrooms in this mixture allows them to soak up all those tangy, herbal notes before they hit the heat.
-
Perfecting the Texture:
For the potatoes, you're looking for that fork-tender stage before mashing them with 1 cup whole milk and 2 tbsp unsalted butter. Sautéing the 1 cup chopped kale for just a few minutes ensures it's wilted but still holds a bit of its spirit.
-
The Final Polish:
Just before serving, taste your mash and add a splash more milk if it feels too thick. A final sprinkle of fresh rosemary or parsley adds that little bit of garden-fresh color to the plate.
-
The Best Moment to Serve:
I find it's best to scoop the mash first and pile those roasted mushrooms right on top while they're still hot. It keeps the potatoes warm and the mushrooms juicy.
- Deglaze your baking sheet with an extra tablespoon of balsamic after roasting to create a rich reduction.
- Try mixing your 4 large russet potatoes with some Yukon Golds for an even creamier, buttery flavor.
- If you don't have fresh thyme, 1 tsp dried thyme works just fine and still gives a lovely depth.
- Ensure your mushrooms are in a single layer on the sheet so they caramelize instead of crowding.

Frequently Asked Questions
→ Can I use a different kind of milk in the potatoes?
Oh, absolutely. Any plant-based milk works just fine in place of the 1 cup whole milk, and it still tastes wonderful.
→ What if my mushrooms are releasing too much water?
That happens sometimes, oops! Just make sure they aren't crowded on the baking sheet so the moisture can evaporate and they can actually brown.
→ How do I store the leftovers?
Keep your mashed potatoes in an airtight container in the fridge for up to 3 days. When you reheat them, just add a tiny splash of milk to bring back that creaminess.

Ingredients
Balsamic Roasted Mushrooms
- 01 16 oz cremini or button mushrooms, cleaned and sliced
- 02 2 tbsp balsamic vinegar
- 03 2 tbsp olive oil
- 04 1 tsp Dijon mustard
- 05 1 tsp fresh thyme leaves (or 1 tsp dried)
- 06 Salt and pepper, to taste
Herby Kale Mashed Potatoes
- 01 4 large russet potatoes, peeled and cubed (about 2 lbs)
- 02 1 cup whole milk (or plant‑based milk)
- 03 2 tbsp unsalted butter (or vegan butter)
- 04 1 cup chopped kale, stems removed
- 05 1 garlic clove, minced
- 06 1 tsp fresh chives, finely chopped (optional)
Garnish
- 01 Fresh rosemary or parsley, for garnish
Instructions
First things first, let's get the oven warming up to 400°F (200°C). I usually line my baking sheet with parchment paper—it just makes cleanup so much easier, honestly.
In a nice large bowl, whisk together your balsamic vinegar, olive oil, Dijon mustard, thyme, salt, and pepper. Now, gently toss in the sliced mushrooms until every single piece is evenly coated in that tangy mixture.
Spread those mushrooms out in a single layer on your baking sheet. Roast them for 15–18 minutes, giving them a little stir halfway through. You're looking for them to be golden brown and beautifully caramelized. Once they're done, just set them aside for a moment.
While those mushrooms are doing their thing in the oven, bring a large pot of salted water to a boil. Pop in your cubed potatoes and let them cook for 12–15 minutes. I just check them with a fork—once they're fork‑tender, they're ready.
Drain the potatoes well and put them back in the pot. Stir in the butter, milk, and minced garlic. Now, just mash them with a whisk or potato masher until they're smooth and creamy. Go ahead and season with salt and pepper to taste.
Meanwhile, heat a tiny bit of olive oil in a sauté pan over medium heat. Toss in the chopped kale and sauté for about 2–3 minutes until it's just wilted. Gently fold that kale into your mashed potatoes and stir in the fresh chives.
Give the mash a quick taste. If it feels a bit too thick, just add a splash more milk or a pinch more salt and pepper until it feels just right.
Now for the best part. Scoop the herby kale mashed potatoes onto plates, top them with a generous helping of those balsamic roasted mushrooms, and drizzle a bit of extra balsamic reduction if you're feeling fancy. Garnish with fresh rosemary or parsley, and you're all set.
