Saucing The Southwestern Style Leftover Turkey Casserole
There are 5 components to a good casserole… the noodles, vegetables and proteins, crispy, buttery topping… and the sauce that binds it all together. The Southwestern Style sauce for this leftover turkey casserole isn’t a shy wallflower. It’s got a punch that cradles and loves the rest of the ingredients.
- Chili Powder
- Dry Mustard
- White Pepper
- Kosher Salt
- Cayenne Pepper
- Chicken Broth
- Half and Half
Making Sauce For Casserole:
- This simple Southwestern style sauce uses the same basic technique as most white sauce recipes (a.k.a. béchamel) but goes a bit deeper. Instead of starting with butter and flour, we start by sautéing the onions in the butter, until tender.
- When the onions are softened and slightly translucent, sprinkle in the spices and stir them around to release their aromas and flavors.
- Then add the flour, stirring until all of the flour has been incorporated and you have a thick paste.
- Next come the liquids… Start with chicken broth, adding a little at a time and stirring constantly. Make sure you scrape the sides and bottom of the pot, so nothing sticks. When all of the liquid has been added, bring the sauce to a boil, stirring constantly for one minute or until the sauce thickens slightly.
- Stir in the half and half and simmer for a minute. Remove from heat.
This leftover turkey casserole gets some of its Southwestern Style from the addition of spicy green chiles and sweet roasted bell peppers. Feel free to use canned green chiles and jarred roasted red peppers for ease. If you have fresh chiles and peppers, here’s how to prepare them yourself…
Roasting Peppers and Chiles
- Roast them in the oven until blackened. Transfer the peppers and chiles to a bowl and cover with plastic wrap.
- Let them rest until they’re cool enough to handle.
- Remove the skins (they will slough off easily), discard the seeds and stems.
- Chop into half inch dice.
Adding Vegetables To Sauce For Casserole
- You can get mild green chiles if you’re heat averse, or step it up with a medium heat. I wouldn’t go beyond that because you want your casserole to have flavor — not JUST HEAT. Incidentally, the roasted bell pepper countermands the heat with a mild sweetness. Stir in the chopped green chiles and roasted bell pepper.
- A can of fire roasted tomatoes along with the peppers and green chiles gives the sauce for the casserole body and layers of flavor. Add them to the sauce and stir to combine.
Assembling Leftover Turkey Casserole
- Finally, stir in the diced leftover turkey and fresh cilantro to the sauce.
- Cook the noodles to just before al dente (the pasta will continue to absorb the sauce and soften as it bakes).
- Mix the Southwestern style sauce for the casserole with the cooked noodles. (I used fusilli pasta, but feel free to use elbow macaroni, ziti, rotini, penne or other tubular pasta).
Adding Cheeses and Assembling The Casserole
I like to wait until the sauce has been combined with the turkey, vegetables and pasta BEFORE adding in the cheese. If the cheese is added in immediately after the broth and half and half, it melts and just becomes part of the sauce. There’s nothing inherently WRONG with that, I just prefer those long, stringy pulls that you get when the cheese is mixed in at the end. You’ll want to reserve a bit of cheese for the topping as well.
Cheese For Leftover Turkey Casserole
I used two types of cheese in this Southwestern style turkey casserole — and because I wanted Southwestern flavors I opted for Cheddar and Colby Jack. You can also use pepper jack, if you want more heat.
Finally a fresh buttered herb breadcrumb topping adds just the right texture and crunch to the soft, lush interior of the casserole.
To Make Crumb Topping:
- Use a few slices of bread (any type — I’ve even used old hot dog buns in a pinch) and rip them apart.
- Transfer bread to a mini food processor.
- Add butter and fresh parsley.
- Pulse until crumbs have formed. The beauty of this buttered herbed breadcrumb topping is that because the bread and butter are processed together, the crumbs are evenly coated with butter. Consequently, they’ll brown and crisp to a golden crunch in the oven.
Serve Southwestern Style Turkey Casserole while it’s hot. I like mine with a simple green salad and chilled white wine. This recipe makes one large casserole or two smaller ones. I admit that sometimes I’ll just freeze one of the casseroles for an easy meal on a night when I don’t feel like cooking, however, if you’ve got a crowd to feed, this should do it!
