Ingredients
- 1 pound fresh asparagus, cut into 1–2 inch pieces
- 1 pound cremini mushrooms, quartered
- 1 medium yellow onion, diced
- 3 cloves garlic, minced
- 4 tablespoons unsalted butter, divided
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1/2 cup vegetable broth
- 1/2 cup heavy cream
- 1/2 cup grated Parmesan cheese
- 1/4 cup grated Gruyere cheese
- 1 tablespoon fresh thyme, chopped
- 2 tablespoons fresh parsley, chopped
- Salt and black pepper to taste
- Pinch of nutmeg
Instructions
1. Preheat your oven to 375°F. Wash asparagus and snap off tough ends, then cut into 1-2 inch pieces. Clean mushrooms with a damp towel and quarter them. Dice onion, mince garlic, and grate both cheeses.
2. Melt 2 tablespoons butter in a large oven-safe skillet over medium heat. Add diced onion and sauté for 5-7 minutes until soft and translucent. Stir in garlic and cook one more minute until fragrant.
3. Add mushrooms to the skillet and cook for 8-10 minutes until they release moisture and brown slightly. Add asparagus and cook another 5-7 minutes until tender-crisp and bright green. Season with salt and pepper, then remove from heat.
4. In a separate saucepan, melt remaining 2 tablespoons butter over medium heat. Whisk in flour and cook for 1-2 minutes, stirring constantly to create a roux. Gradually whisk in milk, a little at a time, until smooth and slightly thickened.
5. Pour in vegetable broth and bring to a gentle simmer. Cook for 5-7 minutes until sauce thickens. Stir in heavy cream, Parmesan, Gruyere, nutmeg, and fresh thyme. Keep stirring until cheese melts and sauce becomes velvety smooth.
6. Pour the creamy sauce over vegetables in the skillet and gently stir to coat everything evenly. If using a baking dish, transfer the mixture now.
7. Bake for 20-25 minutes until bubbly around the edges and golden brown on top. For extra crispiness, broil for the last 1-2 minutes.
8. Remove from oven and let rest for 5 minutes. Sprinkle fresh parsley over the top and serve hot.
Notes
Use fresh asparagus for best texture and flavor. Snap ends where they naturally break.
Cremini mushrooms add depth, but white button mushrooms work too. Never soak mushrooms in water.
Gruyere cheese creates nutty complexity. Substitute with Fontina or Swiss cheese if needed.
Whole milk makes richer sauce than skim. Heavy cream adds luxurious texture.
Grate cheese fresh for better melting quality than pre-shredded.
Don’t skip the ice bath if prepping asparagus ahead of time.
Room temperature milk prevents lumps in the sauce.
Make sauce ahead and refrigerate up to 2 days.
Store leftovers in airtight container in fridge for up to 3 days.
