Boneless Pork Loin Roast
For this recipe we’ll use a boneless pork loin roast of around 3-4 lbs. This is one of the most common pork roasts available at most supermarkets and is outstanding for a family meal.Boneless pork loin is usually very lean. Most will have a “fat cap”, which is a layer of fat on one side. If it’s overly thick, feel free to cut some away. However, we’re going to want to keep some of it, as it adds greatly to the juiciness of the finished recipe.
Only 5 Ingredients
Don’t you just love recipes which only have a few simple ingredients? This means less time prepping and more time enjoying. With this recipe we simply add some salt and pepper directly to the pork roast first, then apply a layer of yellow mustard before topping it off with some crushed potato chips. What?! Yep, you heard that correctly – we’re gonna crust our pork loin with mustard and potato chips. And trust me, it’s glorious!
Let’s start by crushing the potato chips. There’s a couple of ways you can do this. You can place 4-5 handfuls of chips into a food processor and pulse it a few times. Or, place the potato chips in a zip top bag and start crushing. A rolling pin works well with this method too. Oh, and if the kids want to help, this is the best part for them – “Hey kids… come smash some potato chips for me!” Watch them come running.
Ok, with the smashed potato chips out of the way, line a baking sheet or dish with foil to help make for easy cleanup. You can spray a little non-stick cooking spray on it too. Then place the pork roast on the foil. If there’s a layer of fat on the meat, place it so the fat side is up. his will help keep the roast moist during roasting.
Sprinkle some salt and pepper to taste all over the roast and press it in a little. Usually about ½ – 1 tsp of each is good. Now it’s time to slather up the roast with good old yellow mustard. You’ll probably wind up using 2-3 tbs of mustard. If you have a brush, this helps spread it on evenly. If you don’t have a brush, just apply with a knife or spatula and spread it on.
Finally, it’s time for the crushed chips. Go ahead and dump them on and gently press into the mustard covered roast.
Roast at 375°(F) for 60-90 Minutes
Make sure your oven is preheated, then place the roast in the oven at 375°(F) for 60-90 minutes. A 3lb roast will take about an hour. The real key is to monitor the center temperature of the roast. We want to the meat to have an internal temperature of 145°(F). Use a temperature probe of check the temp periodically with an instant read thermometer. To really get the perfectly done meat, take the roast out when that internal temp reaches about 142°(F). The temp will continue to rise when removed from the oven and reach the desired temp.
Pork loin is very lean and can be easy to overcook. It will become very dry and tough if overcooked so be extra sure to keep an eye on the internal temperature.
Let it Rest
When the roast is done, remove from oven and cover lightly with foil and let it rest for about 10 minutes. This will allow all the juices to redistribute throughout the roast.
Slice and Serve!
You’re now ready to enjoy your pork roast! Make sure to use a sharp carving knife and cut into slices of desired thickness. You can also save any juices that may have collected in the pan and pour over the meat.
Goes Well With…
One of the great things about a pork recipe such as this is that is pairs well with a wide variety of side dishes. I’m a huge mac and cheese fan and our Best Damn Instant Pot Mac and Cheese recipe is a favorite side dish for pork roast. Air Fryer Brussels Sprouts are easy and SO good with this pork as well.
Reheating and Storage
You can absolutely cook the roast ahead of time and enjoy it for lunch or dinner during the week as part of meal planning. Simply store the sliced pork in air tight food storage containers for 3-4 days in the refrigerator. For freezer storage, wrap each slice individually with foil or parchment paper, before sealing tightly in an air tight freezer bag.
You can reheat right in the microwave. For best results, add a little water or chicken broth to help regain some of the moisture.Print
