Ingredients

Instructions

  1. Step 1: In a large mixing bowl, combine 2 cups all-purpose flour, 3 large eggs, 1/2 cup milk, and 1 teaspoon salt. Stir vigorously with a wooden spoon until the dough is thick and slightly sticky, about 2 minutes. Set aside to rest for 10 minutes.
  2. Step 2: Bring a large pot of salted water to a rolling boil. Using a spaetzle maker or colander, press the dough through holes directly into the boiling water. Cook the noodles until they float to the surface, about 2-3 minutes. Remove with a slotted spoon and set aside.
  3. Step 3: In a large skillet over medium heat, melt 3 tablespoons butter. Add 2 medium thinly sliced yellow onions and cook for 15 minutes until deeply caramelized, stirring occasionally.
  4. Step 4: Add 12 ounces sliced cremini mushrooms and 2 minced garlic cloves to the caramelized onions. Sauté for 7-8 minutes until mushrooms release their moisture and brown.
  5. Step 5: Pour in 1/2 cup heavy cream, 1/2 teaspoon black pepper, and 1/4 teaspoon freshly grated nutmeg. Stir and cook for 3 minutes until the sauce thickens slightly.
  6. Step 6: Add the cooked spätzle noodles to the skillet and toss gently for 2 minutes to coat noodles in the creamy mushroom ragout. Remove from heat and sprinkle with 2 tablespoons chopped fresh parsley before serving.

How do I store leftover Spätzle Noodles with Creamy Mushroom and Onion Ragout?

How do I scale Spätzle Noodles with Creamy Mushroom and Onion Ragout for a different number of people?
