I think my recipe for Grilled Boneless Pork Chops is a perfect way to cook the thick pork loin chops that many people buy at Costco. Recently I gave this recipe just a slight makeover. Then I served the pork chops for dinner out on the patio to test the improved recipe. My sister Pam, my brother-in-law Kelly, and my friend Sue all gave these pork chops a thumbs up!

The thick pork chops are pounded to make them a bit thinner, marinated all day, and then grilled. With extra-thick boneless pork chops I think those steps are important to keep them from drying out on the grill. I used a marinade of fresh lemon juice, olive oil, Worcestershire Sauce, dried sage, garlic powder, onion powder, Penzey’s Pork Chop Seasoning, and black pepper. And it produced pork chops that were absolutely delicious.

And in these days of high meat prices, I think those thick Costco Pork Chops are still somewhat of a bargain. If you buy them occasionally, I hope you’ll try this recipe which I think will produce the best grilled boneless pork chops you’ve ever made. And for people who care about it, these pork chops are extra low in carbs!

What ingredients do you need?

• thick boneless pork chops
• fresh squeezed lemon juice, I used my fresh-frozen lemon juice
• olive oil
• Gluten-Free Worcestershire Sauce (affiliate link)
• Dried Rubbed Sage (affiliate link)
• Garlic Powder (affiliate link)
• Onion Powder (affiliate link)
• Penzey’s Pork Chop Seasoning (affiliate link), probably optional but really good
• fresh ground pepper to taste

Why do you need to pound the pork chops?

Pounding the pork chops with a meat mallet (affiliate link) or something else that’s heavy makes the pork chops an even thickness so they cook better on the grill without drying out. I think this is quite important.

What if you don’t have every ingredient for the pork chop marinade?

If you don’t have every one of the seasonings I used, make the pork chop marinade with the ones you have!

How to Cook Grilled Boneless Pork Chops without an outdoor grill:

If you don’t have an outdoor grill (or if it’s not grilling season), this recipe can be cooked on a Stove-Top Grill Pan or a George Foreman Grill with good results. (affiliate links) Remember the George Foreman Grill cooks both sides at once, so grilling time is shorter.

How to make Grilled Boneless Pork Chops:

(This is only a summary of the steps for the recipe; please scroll down for complete printable recipe. Or if you use the JUMP TO RECIPE link at the top of the page, it will take you directly to the complete recipe.)

1. I like to trim most of the fat that’s on the edges of the pork loin chops. 
2. If you’re using thick pork chops, don’t skip the step of pounding them to an even thickness before you marinate. I pounded the chops until they were about 1/2 inch thick.
3. Whisk together the marinade ingredients.
4. Marinating all day in a Ziploc bag or glass or plastic container with a snap-tight lid will give best results with thick pork chops like this, and I marinated the ones I cooked for these new photos for eight hours. Longer marinating time is fine.
5. When you’re ready to cook, drain pork into a colander placed in the sink and let the marinade run off while you preheat grill to high heat. (I catch the marinade in a bowl and discard so it doesn’t go down my drain; your choice on that.)
6. Turn heat to medium high when you put pork on the grill. If you want grill marks, lay pork chop on an angle to the grill grates and cook about 3-4 minutes.
7. Then rotate the pork chops so they’re going the opposite way and cook about 3-4 minutes more, or until you see criss-cross grill marks when you lift one pork chop to check. Grill marks are optional but fun!
8. Turn pork to the second side and cook 3-4 minutes more, or until the pork reaches 145F/65C when you test with an Instant Read Meat Thermometer. (affiliate link) 
9. I didn’t get a photo of it, but I like to put the pork chops on a plate, cover with foil, and let them rest for about 5 minutes before serving.
10. Serve the grilled boneless pork chops hot and enjoy!

Make it a Low-Carb Meal:

The grilled pork chop in the photo is served with a simple salad of cucumbers, cherry tomatoes, olives, and Newman’s Own Creamy Caesar Salad Dressing (affiliate link). Pork chops like this would taste great with any of these low-carb side dishes:

• Air-Fryer Asparagus
• Cucumber Salad with Avocado and Feta
• Greek Salad with Peppers
• Middle Eastern Tomato Salad
• Fattoush Lebanese Salad

Grilled Boneless Pork Chops are a great option for outdoor grilling and this is the perfect way to cook those thick boneless pork chops so many people buy at Costco.

Ingredients

Toggle ingredient group

• 4 thick boneless pork chops (see notes)

Marinade Ingredients:

Toggle ingredient group

• 3 T fresh squeezed lemon juice (see notes)
• 1/4 cup olive oil
• 1 T Worcestershire Sauce (use gluten-free if needed)
• 1/2 tsp. dried rubbed sage
• 1/2 tsp. garlic powder
• 1/2 tsp. onion powder
• 1 tsp. Penzey's Pork Chop Seasoning (probably optional but very good!)
• fresh ground pepper to taste

Instructions

1. Trim desired amount of fat from pork chops. (If you like keeping some fat on, cut a few slits in the fat to prevent the edges of the pork chops from curling up when they cook.)
2. If you're using extra-thick pork chops, don't skip the step of pounding the pork chops with a meat mallet (affiliate link) or something heavy until they're about 1/2 inch thick. (The pork chops will spring back a bit when they cook, but the pounding is still worth it!)
3. Whisk together lemon juice, olive oil, Worcestershire Sauce, dried sage, garlic powder, onion powder, Penzey's Pork Chop Seasoning, and fresh-ground black pepper to make the marinade.
4. Put pork chops into a Ziploc bag or glass or plastic container with a snap-tight lid and let them marinate 8-10 hours in the fridge, or longer is okay.
5. When you're ready to cook, drain pork into a colander place in the sink and let the marinade run off while you preheat grill to high heat. (I catch the marinade in a bowl and discard so it doesn't go down my drain.)
6. Turn heat to medium high when you put pork on the grill.
7. If you want grill marks, lay pork chop on an angle to the grill grates and cook about 3-4 minutes (check to see if you have grill marks).
8. Then rotate the pork chops so they're going the opposite way and cook about 3-4 minutes more, or until you see criss-cross grill marks.
9. Turn pork to the second side and cook 3-4 minutes more, or until pork reaches 145F/65C when you test with an Instant Read Meat Thermometer. (affiliate link)
10. I like to put pork chops on a plate and cover with foil and let them rest at least 5 minutes, but that's probably optional.
11. Serve the Grilled Boneless Pork Chops hot, and wait for compliments!

Notes

I used the extra-thick pork loin top loin pork chops from Costco.

I use my fresh-frozen lemon juice for this recipe. I  use 3 tablespoons lemon juice, but I really like lemon so you might want a bit less if you're not such a lemon fan.
