Balsamic Roasted Mushrooms with Herby Kale Mashed Potatoes

January 19, 2019

While planning my menu for week 3 of my Vegetarian Challenge, I took inventory of my pantry and noted that I still had about two pounds of potatoes left over from week one that needed to be used ASAP. I decided to make a version of my Fluffy Garlic Herb Mashed Potatoes, but modified to use up some of my leftover sour cream. I stirred in some sautéed kale to make the potatoes colcannon-esque, and topped them with some balsamic roasted mushrooms for a “meaty” element to the dish. The results were amazing and this might be my favorite recipe from the challenge thus far!!

Meal Prep It!

This dish holds up super good in the refrigerator, so it’s perfect for meal prep! I probably won’t have a chance to test it in the freezer though, because I’m eating through it so fast.

Balsamic Roasted Mushrooms with Herby Kale Mashed Potatoes

Shout out to Aldi for having amazing prices on mushrooms. I was able to get one pound of mushrooms for less than 1/2 pound would cost at other stores, making this recipe ULTRA affordable.

Balsamic Roasted Mushrooms with Herby Kale Mashed Potatoes

These Balsamic Roasted Mushrooms with Herby Kale Mashed Potatoes are a vegetarian meal that will please any “meat and potatoes” style meal lover.

Balsamic Roasted Mushrooms

1 lb. mushrooms ($2.58)
1 Tbsp olive oil ($0.16)
3 Tbsp balsamic vinegar ($0.33)
1/2 Tbsp brown sugar ($0.02)
1 Tbsp soy sauce ($0.06)
2 cloves garlic, minced ($0.16)
1/4 tsp dried thyme ($0.02)

Herby Kale Mashed Potatoes

2 lbs. russet potatoes ($1.08)
6 oz. kale, chopped ($1.68)
1 Tbsp olive oil ($0.16)
3/4 tsp salt, divided ($0.04)
1/2 cup sour cream ($0.45)
1/2 cup milk ($0.17)
1 tsp dried parsley ($0.10)
1/2 tsp dried oregano ($0.05)
1/2 tsp dried basil ($0.05)
1/4 tsp garlic powder ($0.02)
1/4 tsp onion powder ($0.02)
freshly cracked pepper ($0.02)

Preheat the oven to 400ºF. Wash the mushrooms and cut them in half if they are large.
In a small dish, stir together the olive oil, balsamic vinegar, brown sugar, soy sauce, minced garlic, and thyme. Place the mushrooms in a casserole dish big enough to allow them to be in a single layer. Pour the balsamic marinade over top and stir until the mushrooms are coated.
Transfer the the mushrooms to the preheated oven and roast for 45 minutes, giving them a stir every 15 minutes. After 45 minutes the mushrooms should be tender and there should be a nice sauce in the bottom of the dish.
Meanwhile, prepare the mashed potatoes. Peel and dice the potatoes into one-inch cubes. Rinse the cubes well in a colander, then place them in a large pot, add 1/2 tsp salt, and cover with cool water. Place a lid on the pot, bring it up to a boil. Boil the potatoes until they are very tender (about 7-10 minutes).
Once the potatoes are very tender, drain them in the colander and rinse them briefly with hot water. Let the potatoes drain in the colander as you prepare the kale.
To the pot used to boil the potatoes, add the chopped kale, 1 Tbsp olive oil, and 2 Tbsp water. Sauté over medium heat just until wilted (3-5 minutes), then remove the kale from the pot.
Return the drained potatoes to the pot along with the sour cream, milk, dried parsley, oregano, basil, garlic powder, onion powder, 1/4 tsp salt, and some freshly cracked pepper. Mash the potatoes until smooth, then taste and add more salt if needed. Stir in the sautéed kale.
To make the bowls, add 1/4 of the herby kale mashed potatoes to each bowl, then top with 1/4 of the balsamic roasted mushrooms. Drizzle a spoonful or two of the juices from the bottom of the casserole dish over the mushrooms and mashed potatoes.

Step by Step Photos

Preheat the oven to 400ºF. In a small dish, stir together 1 Tbsp olive oil, 3 Tbsp balsamic vinegar, 1/2 Tbsp brown sugar, 1 Tbsp soy sauce, 2 cloves of garlic (minced), and 1/4 tsp dried thyme.

Wash 1 lb. mushrooms and slice any large mushrooms in half. Place the mushrooms in a casserole dish that is large enough for them to be in a single layer. Pour the prepared marinade over top and stir to coat.

Transfer the mushrooms to the oven and roast for 45 minutes, stirring every 15 minutes (the photo above is what they look like BEFORE roasting).

After roasting the mushrooms should be tender and there should be a nice sauce in the bottom of the dish.

While the mushrooms are roasting, prepare the herby kale mashed potatoes. Peel and dice 2 lbs. potatoes into one-inch cubes. Rinse the potatoes well, then transfer them to a large pot, add 1/2 tsp salt, and cover with water. Place a lid on the pot, bring it up to a boil, then boil the potatoes until they are very tender (7-10 minutes). Drain the cooked potatoes in the colander and give them a quick rinse with hot water. Let the potatoes sit in the colander as you quickly sauté the kale.

Add 6oz. chopped kale to the pot used to boil the potatoes, along with 1 Tbsp olive oil, and 2 Tbsp of water. Sauté the kale over medium heat until it is wilted (about 3-5 minutes), then remove it from the pot to a clean bowl.

Add the drained potatoes back to the pot along with 1/2 cup sour cream, 1/2 cup milk, 1 tsp dried parsley, 1/2 tsp oregano, 1/2 tsp basil, 1/4 tsp garlic powder, 1/4 tsp onion powder, 1/4 tsp salt, and some freshly cracked pepper. Mash the potatoes until smooth, then taste and add more salt if needed.

And finally, stir the sautéed kale back into the mashed potatoes.

And then to build your bowls simply add 1/4 of the herby kale mashed potatoes and 1/4 of the balsamic roasted mushrooms to each bowl, and drizzle a little bit of the sauce from the roasting pan over top of each. Then dig in!
