Why this recipe works

If you’re looking for the best way to marinade and roast a pork loin, go no further than trying out this Best Herb & Lemon Pork Loin Marinade.

I love how the herbs, lemon juice, and other ingredients in the marinade add so much flavor to the meat and tenderizes the pork.

Add brown rice or quinoa, and an easy to heat frozen vegetable like green beans, and you have an amazing meal the whole family will love.

I especially like how this best marinated pork loin recipe uses a natural, no calorie sweetener like stevia powder or monk fruit powder.

These natural sweeteners are ideal for lowering the calories in marinades. They're also terrific for anyone on low carb or keto diets.

This easy pork loin roast marinade is so versatile that it would also work well with chicken at your next football bowl watching party!

Tips for best marinated pork loin

Start this recipe for marinated pork loin in the morning before leaving for work.

When you come home, get it roasting in the oven while you get started on the side dish, salad, and if you feel up to it, a yummy dessert.

Or sit back and enjoy a cocktail and catch up with your spouse and kids.

If you’re gluten free, make sure to use tamari sauce and not soy sauce in this best marinade for pork loin, since most soy sauces contain wheat.

If you don’t have club soda, plain seltzer is OK to use in this marinated pork loin recipe.

You’ll want to baste the pork loin with a soup ladle not a turkey baster. The pork loin marinade is too thick and will clog up your baster.

Use my favorite meat tenderizer tool from my carne asada marinade recipe.

I also use Jaccard Tenderizers when I marinade chicken.

The Jaccard Meat Tenderizer is one of my favorite kitchen gadgets and one of my readers’ favorites, too!
