Ingredients

3 tablespoons butter
1/4 cup diced onion
1/4 cup diced celery
3 tablespoons flour
1 cup milk (can add more if it thickens too much)
2 cups shredded cheddar cheese
1/2 cup sour cream
1 cup frozen peas
1 cup frozen corn
1 cup diced cooked potato
2 cups diced ham
1/4 teaspoon pepper
1/8 teaspoon cayenne (or to taste)
1/4 teaspoon salt (or can omit since ham and cheese are salty)

Preparation

Melt butter in a large Dutch oven or oven safe heavy bottom pot.
Add onions and celery and saute for 1-2 minutes until softened.
Whisk in flour and cook for 1-2 minutes.
Whisk in milk a little at a time and cook until just beginning to boil and sauce has thickened.
Remove from heat and add 1 and 1/2 cup of the cheese and stir until incorporated.
Stir in sour cream.
Add ham, potatoes, corn and peas.
Cover and place in 375 F (190 C) oven for 25 minutes.
