I came across this recipe at a grocery store. It was really yummy, although the original recipe was a bit spicy for my family (and we really like spicy food). I think the key is to adjust the amount of red pepper flakes to taste, because the amount of heat in curry powder can vary wildly. I have very hot curry powder, so the combination of it and 1/2 teaspoons of red pepper flakes was too much. I'm giving the amount here as half that.
Curried Winter Squash with Apples
2 tsp curry powder
1/2 tsp salt
1/4 tsp red pepper flakes
2 cups winter squash, peeled and cubed
1-1/2 cups diced onion
1 baking apple (Granny Smith, Johnagold, etc.)
2 Tbsp olive oil
2 Tbsp butter
Mix together curry powder, salt and red pepper flakes in a large bowl. Mix in squash, onion, apple and olive oil. Pour into a large shallow baking dish. Roast at 375F for 40 minutes. Mix in butter, and roast 5 minutes more.
