OK, yesterday I promised to post a couple of recipes to help you use up some of your leftover grilled pork tenderloin from my 2 recent posts starring this fabulous cut of pork.

Now I realize, having leftover meat is not a bad thing, in fact it’s a great thing. But what to do with it can sometimes be daunting. So this is what I did to utilize the leftover pork tenderloin from my recipe for Grilled Pork Tenderloin with Bourbon BBQ Sauce. I made a casserole. And oh boy was it good. And no, I didn’t use the leftover BBQ sauce. But the pork itself was seasoned perfectly for the other ingredients in this casserole. (You’d think I actually planned it that way. But boy would you be wrong. Just a lucky coincidence!)

For the rest of the casserole, I only used ingredients I happened to have on hand, so no trip to my local grocer was necessary. So if you decide to try this recipe, you too can use what you happen to have on hand. No red bell pepper, no problem. Swiss cheese, but no cheddar – knock yourself out. Hate peas – who cares! It’s a casserole using leftover meat – make it your own. This recipe is just a suggestion for what to do when staring at leftover pork tenderloin in your refrigerator and not wanting to serve it exactly like you did the previous evening.

Of course, you could always just thinly slice the meat, then gently warm it in the leftover BBQ sauce, and slather it between two halves of a lovely, crispy bun. But what fun would that be, when instead you could empty out your refrigerator veggie bin and have leftover casserole for your next days’ lunch? Your welcome!

• 5 T. butter, divided
• 2 T. flour
• 1½ c. milk (I use whole milk)
• ¼ tsp. kosher salt
• freshly ground black pepper
• 1 tsp. dried parsley
• pinch crushed red pepper flakes, opt.
• 1 tsp. Dijon mustard
• 2 tsp. Worcestershire sauce
• ½ c. diced onion
• ½ c. finely diced celery
• ¼ c. red bell pepper, finely diced
• 6-8 sliced fresh mushrooms
• 2 garlic cloves, finely minced
• ½ c. sour cream, or more to taste
• 1½ c. grated sharp cheddar cheese
• ½ c. frozen petite peas
• 2 c. egg noodles, cooked al dente and drained 
• 2 c. thinly sliced cooked pork tenderloin, cut into narrow strips  
• ¾ c. Panko breadcrumbs

Melt 2 tablespoon of the butter in a small saucepan. Whisk in the flour and stir for about a minute. Gradually whisk in the milk and cook until the sauce is thick and creamy. Take off heat and stir in the salt, pepper, parsley, crushed red pepper, Dijon mustard, and Worcestershire sauce. Set aside.

Melt 2 tablespoons of the butter in a large skillet over medium heat. Stir in the onion, celery, red pepper, and mushrooms; sauté until the onion turns translucent. Don’t allow the veggies to brown. Stir in the garlic and cook for one minute.     

Remove pan from heat and stir in the prepared sauce and sour cream until well combined. Then add the cheese, peas, cooked noodles, and cut pork. Adjust seasoning.

Dollop mixture into a lightly greased 9×13-inch baking dish (preferable glass) or ceramic casserole dish.

Melt the final 1 tablespoon butter in a small pan. Stir in the Panko. Sprinkle topping evenly over the casserole.

Bake in a preheated 325 degree oven for 35-40 minutes, or until bubbly and the topping is a nice golden brown.
