Ingredients
 

Main Ingredients

  • 1 tbsp olive oil
  • 3 cup asparagus, cut into 1-inch pieces
  • 2 cup diced cooked ham
  • 3 cup cooked rotini pasta drained well
  • 10.5 oz condensed cream of mushroom soup
  • 0.75 cup milk
  • 1 tbsp Dijon mustard
  • 0.5 cup diced onion
  • 2 tsp minced garlic
  • 1.25 cup shredded sharp cheddar
  • 0.5 cup shredded mozzarella
  • 0.5 tsp kosher salt reduce if ham is very salty
  • 0.5 tsp black pepper
  • 0.75 cup panko breadcrumbs
  • 2 tbsp unsalted butter, melted
  • 2 tbsp grated Parmesan

Instructions

Preparation Steps

  • Heat oven to 375°F. Lightly grease a 9×13-inch baking dish.
  • Boil pasta in salted water until just shy of al dente. Drain and set aside.
  • Warm olive oil in a large skillet over medium heat. Soften onion for 3 minutes.
  • Stir in garlic and cook 30 seconds. Add asparagus and sauté 3–4 minutes until bright and crisp-tender.
  • Whisk soup, milk, Dijon, salt, and pepper in a bowl until smooth.
  • Combine pasta, ham, sautéed vegetables, sauce, and half the cheddar in a large bowl.
  • Spread mixture in the baking dish. Top with remaining cheddar and all the mozzarella.
  • Mix panko with melted butter and Parmesan. Sprinkle evenly over the casserole.
  • Bake 25–30 minutes until bubbly and golden. Rest 10 minutes before serving.

Notes

Try Swiss or Gruyère instead of cheddar for a classic ham-and-asparagus pairing. Stir in 1 cup sliced mushrooms with the onion if you like. To make ahead, assemble, cover, and refrigerate up to 24 hours; add 5–10 minutes to bake time. Leftovers keep 3–4 days refrigerated; reheat covered at 325°F until warm.
