All the richness of roasted mushrooms, the creaminess of the sour cream, handfuls of fresh herbs all served over pasta- comfort food extraordinaire!
Roast for 15 minutes.
While the mushrooms are almost finished roasting, In a large fry pan over medium-high heat, melt the butter and remaining 3 tbsp olive oil. Add the shallots and sauté until lightly golden, 2 to 3 minutes.
Add the roasted mushrooms and cook, for about 2 minutes. (If using the chestnuts, add at this time as well)
Whisk the flour with the porcini powder (if using) in a small bowl. Add the flour into the pan and stir to incorporate. Stir in the wine and let it simmer for about four minutes to cook off the alcohol. Add the broth and stir well to combine. Reduce the heat to medium low and let it simmer for two minutes.
Meanwhile, bring a large pot of water to a boil over high heat. Add a good amount of salt, and the pasta to the boiling water. Cook until al dente, according to the package instructions. Drain, reserving about 1/2 cup of the cooking water.
Garnish with more parsley and dill and serve.
Beef stock will make this dish taste the most like a traditional Stroganoff. If you want to keep it vegetarian, and you don't have vegetable stock on hand, this is a perfect time to use the Faux Chicken Bouillon Powder from my Pantry. It is so easy to add a tbsp of the powder to your measuring cup and add the water and blend. Adding this and the wine to the pan will make a wonderful sauce. Totally vegetarian this way!
