This rich mushroom stew with root vegetable mash is my answer to a chilly evening when all I want is comfort in a bowl. Loaded with earthy mushrooms and a tangle of sweet and savory root vegetables this dish feels both nourishing and decadent. The aromatic stew is ladled generously over a creamy mash that soaks up every bit of the silky gravy.

I remember the first time I cooked this for my friends on a rainy December night and it’s been a special request ever since. The aroma alone brings everyone to the kitchen.

Ingredients

  • Mushrooms: Choose mixed varieties such as cremini shiitake and portobello for layers of earthy flavor Pick mushrooms that are firm and fresh without slimy spots

  • Garlic cloves: Freshly minced for aromatic depth Use cloves that are plump and not sprouting
  • Carrots: Provide subtle sweetness and color Look for firm carrots with no green tops

  • Salt and ground black pepper: Essential for seasoning Always taste and adjust at the end
  • Chopped parsley: Freshens up the bowl
  • Potatoes (for the root vegetable mash): Opt for floury types such as Yukon Gold for a creamy base
  • Parsnips: Add sweetness and earthiness Choose smaller roots for tenderness
  • Celeriac: Subtle celery flavor and creaminess Firm bulbs without blemishes are best
  • Milk or plant based milk: Helps smoothen the mash
  • Unsalted butter or vegan butter: Adds richness and sheen
  • Salt and pepper: Essential for final flavor balance

Instructions

Prepare the root vegetable mash:
Place cubed potatoes parsnips and celeriac in a large pot Cover completely with cold salted water This ensures even cooking Bring to a boil over high heat then reduce to a simmer Cook for twenty to twenty five minutes until all vegetables are easily pierced with a fork Drain and set aside until ready to mash
Sauté the aromatics:
While the mash cooks heat olive oil in a heavy pot over medium heat Add chopped onion carrots and celery Stir often letting them sizzle for five to seven minutes until they are very soft and fragrant but not browned This low slow process forms the flavor base
Build the mushroom stew:
Add garlic to the pot and stir continuously for one minute until you smell the aroma Pile in the sliced mushrooms Stir well and let them cook uncovered for eight to ten minutes Stir now and then so they brown all over and release their moisture When most liquid has simmered away they should be deeply colored
Layer in flavor:
Stir in the tomato paste thyme and smoked paprika Add the soy sauce and cook for two full minutes letting the paste caramelize This step intensifies the overall depth and blends the seasonings
Deglaze and simmer:
Pour in the red wine Scrape the bottom of the pot with a wooden spoon to pick up any browned bits Simmer gently for two to three minutes so the wine reduces and loses its raw edge
Add broth and simmer again:
Pour in the vegetable broth Add the bay leaves Bring everything to a gentle simmer Cover and cook for fifteen minutes which melds flavors Then remove the lid and continue to simmer for an additional five to ten minutes to reduce and thicken
Finish the stew:
Stir the prepared cornstarch slurry into the bubbling liquid Stir constantly for two to three minutes until the stew takes on a glossy sheen Taste and season with salt and pepper Remove and discard bay leaves
Mash the vegetables:
Return the drained potatoes parsnips and celeriac to their pot Add milk and butter Mash until completely smooth and creamy Season to taste with salt and pepper The texture should be fluffy and lump free
Plate and serve:
Spoon a large scoop of mash into each bowl Top with generous ladles of mushroom stew and a sprinkle of chopped parsley Serve hot

What I love most is how the mushrooms soak up all the wine and broth They become melt in your mouth and even my mushroom skeptics ask for seconds My kids consider this our wintertime comfort blanket in a bowl

Storage Tips

Keep leftovers in an airtight container in the fridge for up to four days The flavor deepens overnight For freezing let the stew and mash cool completely and pack portions separately in freezer containers Defrost gently in the fridge overnight then reheat on the stove with a splash of broth or milk

Ingredient Substitutions

No celeriac Try rutabaga or an extra potato Prefer a different herb Rosemary or sage both work beautifully If you cannot find portobellos double up on cremini and add a handful of dried porcini soaked in warm water for richness

Serving Suggestions

A big green salad and a hunk of crusty bread complement the richness For extra brightness a squeeze of fresh lemon over the stew just before serving works wonders I love this paired with a peppery arugula salad drizzled with balsamic Reduction

How to Make It

Step 01

Cook the Root Vegetables: Place potatoes, parsnips, and celeriac in a large pot. Cover with cold, salted water and bring to a boil. Reduce the heat and simmer for 20 to 25 minutes, until the vegetables are tender.

Step 02

Sauté the Aromatics: While the vegetables cook, heat olive oil in a large heavy-bottomed pot over medium heat. Add onion, carrots, and celery and sauté for 5 to 7 minutes until softened.

Step 03

Add Garlic and Mushrooms: Stir in garlic and cook for 1 minute, then add the sliced mushrooms. Sauté for 8 to 10 minutes, stirring occasionally, until mushrooms are nicely browned and most of their liquid has evaporated.

Step 04

Incorporate Seasonings: Mix in tomato paste, thyme, smoked paprika, and soy sauce. Cook for 2 minutes, allowing flavors to blend.

Step 05

Deglaze and Reduce: Pour in dry red wine, scraping up any browned bits at the bottom of the pot. Simmer for 2 to 3 minutes until slightly reduced.

Step 06

Simmer the Stew: Add vegetable broth and bay leaves. Bring to a simmer, cover, and cook for 15 minutes. Remove lid and simmer an additional 5 to 10 minutes, allowing the stew to thicken.

Step 07

Thicken the Stew: Stir in the cornstarch slurry. Simmer for 2 to 3 minutes more, until the stew turns silky and glossy. Season with salt and pepper. Discard bay leaves.

Step 08

Prepare the Mash: Drain the cooked root vegetables and return to the pot. Add milk and butter. Mash until smooth and creamy. Adjust seasoning with salt and pepper, as desired.

Step 09
