This asparagus au gratin recipe is made with cheese, asparagus, walnuts, and cracker crumbs.

The casserole makes a fabulous side dish, and it's very easy to prepare and bake. The chopped walnuts make the cracker crumb mixture crunchy and flavorful.


  • 5 tablespoons butter, divided
  • 1 teaspoon salt
  • 3 tablespoons all-purpose flour
  • 1/4 teaspoon freshly ground black pepper, optional
  • 1 1/2 cups milk
  • 1 cup shredded cheddar or Gruyere cheese
  • 1 1/2 cups cracker crumbs
  • 1 cup chopped walnuts
  • 2 cups cooked chopped asparagus

Steps to Make It

  1. Heat the oven to 350 F.

  2. Butter a 1 1/2-quart casserole.

  3. In a saucepan over medium-low heat, melt 3 tablespoons of butter; stir in salt and flour. If desired, add 1/4 teaspoon of freshly ground black pepper, if desired.

  4. Cook the flour mixture for about 2 minutes, stirring constantly.

  5. Gradually add the milk while stirring.

  6. Add shredded cheese and cook, stirring, until thickened.

  7. Remove the sauce from the heat.

  8. Melt the remaining 2 tablespoons of butter.

  9. Combine cracker crumbs with the melted butter and chopped walnuts; toss to blend. Reserve a few tablespoons for topping.

  10. In the prepared casserole dish, place a layer of asparagus, a layer of cracker and walnut mixture, then a layer of sauce.

  11. Repeat the layers, ending with the reserved crumbs.

  12. Bake in the preheated oven for about 25 to 30 minutes, or until top is nicely browned.
