Ingredients

Instructions

  1. Step 1: In a large bowl, whisk together 2 cups all-purpose flour, 1 tsp salt, 3 large eggs, and 1/2 cup milk until a thick, sticky batter forms. Let rest 10 minutes.
  2. Step 2: Bring a large pot of salted water to a boil. Using a Spätzle maker or colander, press the batter through the holes into the boiling water. Cook the noodles until they float to the surface, about 2 minutes, then scoop out with a slotted spoon and set aside.
  3. Step 3: In a large skillet, melt 2 tbsp butter over medium heat. Add 2 thinly sliced medium yellow onions and cook slowly for 15 minutes, stirring frequently, until deeply caramelized and golden brown.
  4. Step 4: Add 3 tbsp butter, 10 oz sliced cremini mushrooms, and 1 minced garlic clove to the onions. Sauté for 7 minutes until mushrooms are tender and the mixture is fragrant.
  5. Step 5: Pour in 1 cup vegetable broth and simmer for 5 minutes until reduced slightly. Stir in 1/2 cup heavy cream and 1/4 tsp black pepper, cooking for another 3 minutes until the gravy thickens.
  6. Step 6: Add the cooked Spätzle to the skillet and gently toss to coat in the mushroom and onion gravy. Warm through for 2 minutes.
  7. Step 7: Garnish with 2 tbsp chopped fresh parsley and serve immediately.
