Fabulous main dish casserole with ham, potatoes, sweet potatoes, onions, leeks & garlic in a thick, cheese sauce with parsley, thyme and marjoram. This wonderful comfort food is terrific for either company or family meals. Gluten free.
Ingredients
- 1 1/2 lbs. ham sliced in thin strips
- 2 large sweet potatoes peeled
- 4 medium Russet potatoes peeled
- 2 leeks green tops removed, sliced
- 1 medium onion diced
- 1 heaping tablespoon minced garlic from a jar (or about 3 cloves fresh garlic, finely minced)
- 3-4 cups half-and-half or heavy cream as desired, depending on how thick you want the sauce
- 1 stick unsalted butter (1/2 cup)
- 1 1/2 cups gluten free flour (or use regular flour)
- 8 oz. sharp cheddar cheese grated
- 1 tsp. dried marjoram
- 1 tsp. dried thyme
- 1 tsp. kosher or sea salt
- 1 tsp. pepper
- 1 tbsp. dried parsley
Instructions
- Spray a 10x15” glass baking dish with olive oil cooking spray.
- Peel sweet potatoes, slice down and then cut each slice in thin strips.
- Layer into prepared casserole dish.
- Peel white potatoes. Cut in ¼ to 1/3” disks and then cut down in larger pieces.
- Toss on top of sweet potatoes.
- Sprinkle diced onion over top of potatoes.
- Add sliced leeks and then garlic.
- Slice ham down into strips and layer on top of everything else.
- To make sauce: place butter in medium to large saucepan and place over low to medium heat.
- Whisk in flour. It will be dry and lumpy.
- Add half-and-half about a quarter cup at a time and whisk into mixture.
- Continue adding half-and-half up to three cups while working out the lumps from the flour. (Add an additional cup of half-and-half or milk if you don't want an incredibly thick sauce).
- Add cheese, marjoram, thyme, parsley, salt and pepper.
- Stir and continue cooking until sauce thickens.
- Allow to thicken again.
- Pour sauce over top of ham and potatoes.
- Cover with foil. Bake at 350° for about an hour.
- Remove foil. Check to be sure potatoes are fork tender.
- Stir all ingredients and place back in oven another 5 or 10 minutes to lightly brown top of casserole.
Notes
NOTE: If you like a really thick sauce use 3 cups of cream, otherwise use the whole 4 cups for a normal cheese sauce texture. You can also cut this with a couple of cups of milk if you don’t want your sauce this thick.
