  • Preheat oven to 400°F.
  • Butter a 3 quart casserole dish.
  • In a large skillet, cook the mushrooms in 1 1/2 tablespoon of the butter over medium heat, stirring, about 5 minutes. Set aside.
  • In a large, dutch oven, melt 1/4 cup of butter. Stir in the flour, and cook the mixture over low heat, whisking constantly for three minutes. Remove from the heat.
  • Slowly whisk in the broth until smooth.
  • Then whisk in the milk and heat on a medium flame, whisking constantly, simmering for one minute. Then stir in the sherry and simmer for one more minute.
  • Remove from the heat. Flavor with lemon juice, nutmeg, salt and pepper to taste. Add the cooked spaghetti, ham, cheddar cheese and mushrooms to the sauce and toss.
  • Transfer the entire mixture to the buttered casserole.
  • In a separate pan melt 2 tablespoons butter and then mix in 1 cup panko bread crumbs until the butter is thoroughly absorbed. Sprinkle the mixture evenly over the tetrazzini. Dot the top with the a tablespoon of butter, cut into small pieces.
  • Bake uncovered on the middle rack of the oven until the sauce is bubbly and the top is golden, about 20 minutes. Serve and enjoy.


  • Looking for a delicious gluten free spaghetti? You may want to try Tinkyada spaghetti this time as I did. I love that it's never mushy and always tastes great. Schar spaghetti and Sams Mills pasta d’oro are also good.
  • If you prefer ham with no added nitrates or nitrites, no artificial ingredients or preservatives as I do, you may find this one at Whole Foods.
  • No leftovers? No problem. You can ask your deli person to slice ham 1/4-inch thick for you. Then just cut it up into bite-size pieces.
  • Using a large skillet to cook the mushrooms will give the mushrooms plenty of room so that they can brown. Add butter to the skillet and cook your mushrooms, tossing them with a wooden spoon until they’re brown (about 5 minutes).
  • Place your casserole on a baking sheet so that if it bubbles over, the baking sheet will catch all the drippings. 
  • You might like to add more vegetables to your casserole. Sweet peas are a popular choice.
