Grilled Pork Chops with Guinness Barbecue Sauce and Cheesy Mashed Potatoes
I love grilling pork chops because it is a fast and easy way to prepare a protein-rich meal without too much work (or dishes). Our Guinness-based BBQ sauce gives the chops incredible flavor. It’s a great use for that extra bottle of stout, and the sauce itself keeps well for future meals and freezes well, too.
This recipe features our custom OWYD Spicy Pork Rub. It has a hint of spice, but nothing too crazy. Spice lovers will think it is super mild, people intolerant to spice will probably call it “spicy”. Either way, pick some up. We use it on pulled pork, in our chili recipes, and even on chicken when we want a bit of a different flavor profile than our Roasted Chicken Rub provides.

Grilled Pork Chops and Guinness BBQ Sauce Shopping List
Wondering if you have to hit the store? Here’s the list of items you’ll need to make this recipe. For specific amounts, please refer to the printable recipe card at the bottom of the post.
Ingredients
- Center-Cut Pork Chops – A uniform cut that grills evenly and holds up well to bold seasoning.
- OWYD Spicy Pork Rub – Pick some up, ASAP! If you don’t have any (yet) but want to make this anyway, you can sub in your favorite pork rub.
- Guinness – Guinness-lovers unite! This is a perfect way to use some of your stash.
- Ketchup – The perfect barbecue sauce base, in my opinion. All of my homemade BBQ sauce recipes use it.
- Apple Cider Vinegar – A little vinegar is necessary in any good barbecue sauce. It adds sharp acidity to cut through the richness.
- Soy Sauce – Great for boosting the umami and saltiness.
- Worcestershire Sauce – Worcestershire sauce contains anchovies, so keep that in mind if you are serving anyone with allergies!
- Minced Garlic – Fresh only, please! Put the jarlic away. 😉
- Dry Mustard Powder – This should be a staple in your spice cupboard.
- Yellow Mustard – You can sub in Dijon or stone ground mustard if you’d like.
- Black Pepper – Freshly ground works best!
- Minced Onion – You can use onion powder if you don’t have fresh onion.
- Garlic Salt – Garlic powder also works here. Taste and add a little extra salt if you need to.
- Red Pepper Flakes – For some heat! If you can’t take the heat, omit it from the sauce.
- Russet Potatoes – High starch content makes them ideal for fluffy mashed potatoes, but reds or yellows will work in a pinch.
- Salted Butter – If you use unsalted butter, you’ll need to add a little extra salt.
- Heavy Cream – Don’t sub in milk for this part, please. Half and half would be acceptable.
- Kerrygold Dubliner Cheese – A sharp, slightly sweet Irish cheese that has the perfect melt and blends well into the potatoes.
- Salt & Pepper – Season to taste. How much salt you’ll need to add depends on how much the potatoes absorbed while cooking.

FAQ
How should I store leftovers?
Keep leftover pork chops in an airtight container in the fridge for up to 4 days. Store the mashed potatoes separately.
Can I reheat the pork without drying it out?
Yes. Warm slices in a covered skillet over low heat with a splash of broth or extra sauce to keep them juicy.
Can this be made ahead?
You can make the BBQ sauce up to 5 days in advance and refrigerate. Mashed potatoes can be prepped and reheated with a splash of cream to loosen them.
What can I substitute for Guinness?
Use any dark stout or porter-style beer. For a non-alcoholic option, try beef broth with a touch of molasses.
Can I use boneless pork chops?
Yes, but reduce the grilling time slightly since they cook faster and can dry out more quickly.
