Grilled Potatoes with Basil Vinaigrette is a marriage made in food heaven. My only advice with this one is to make extra. Everyone will want seconds and they’re great heated up for leftovers.

Tired of the same old mashed potatoes dripping in butter or a big steamy baked potato crowned with a dollop of sour cream? Heck no! Me neither! But this is a great side dish recipe to have in your back pocket.
I am very pleased to announce that Tony’s Market has asked me to be Blogger Ambassador for their Dry Creek location. Throughout the years, I’ve made my passion for Tony’s Market no secret and have blogged about the store upteen times.

I affectionally refer to Tony’s on Dry Creek as “my Tony’s.”
It’s close to home and my relationship with that original location began over thirty years ago when I became a customer. It was only a meat market then…a small store with a meat counter where I could be guaranteed to purchase the best steak in town. This is a photo from 1978, with THE Tony Rosacci behind the counter.
For September, Tony’s requested the theme be “What’s good on the grill … besides a cheeseburger.” Well, I’ll tell you what’s good on my grill are these red grilled potatoes with Aspen Cornucopia Basil Vinaigrette.

With all of the new potatoes available now, and our stunning Colorado late Summer weather, this is a great time to fire up that grill.
This all natural farm-to-table vinaigrette is made locally with fresh basil picked from Osage Gardens in New Castle, Colorado and bottled within two days. Like Summer in a bottle, the mustard and basil add zing to salads or grilled fish and chicken.
It was a perfect pairing for these grilled potatoes. The flavor was light enough not cover the sweet flavor of new potatoes.
Let’s grill those potatoes, and we start with cooking them on the stove. Did you know there’s a right way to boil potatoes? And the wrong way is to throw them in a pot of water and turn the heat up to high.
- Gently place potatoes into a pot of cold salted water. The water should cover the potatoes by one inch.
- Turn the heat on to medium high and slowly heat until water just begins to boil. Reduce heat to maintain a simmer. Don’t let the water get hot enough to where the potatoes bounce around.
- Cook until just before desired doneness. Drain potatoes in a colander and let them sit until cool to the touch.
Since I’m going to finish these potatoes on the grill, I’ve cooked them until just tender and then sliced them in half. The grill will crisp them up nicely.

Grilled Potatoes with Basil Mustard Vinaigrette
Ingredients
- 2 pounds new red potatoes washed and scrubbed
- 1 tablespoon salt
- 1/2 cup Basil Vinaigrette
- Zest of 1 lemon
- 3 ribs celery trimmed and fine chopped
- 1 bunch green onions thin sliced
- 1/2 cup parmesan cheese grated
Instructions
- Place potatoes and salt in a large pot and cover with cold water by 1 inch. Heat over medium high heat until water just begins to boil. Reduce heat to maintain a simmer and cook potatoes until tender but not completely cooked through, about 8 to 10 minutes for medium small potatoes. Drain potatoes in a colander and let cool to the touch. Slice potatoes in half and set aside.
- Dice your celery and onions.
- Prepare a medium heat either on a charcoal or gas grill. Or heat a large grill pan over medium beat. Brush grates with a thin layer of vegetable oil. Place potatoes on a bowl and pour in a little oil and toss to just coat the potatoes. Place the potatoes, cut side down on grill. Cook until dark grill marks develop, about 3 – 4 minutes. Using tongs, flip potatoes and cook until golden brown and cooked through, another 3 – 4 minutes.
- In the meantime add the diced celery, onions and basil vinaigrette to the bowl that you tossed the potatoes in the oil. Transfer the cooked potatoes to this bowl and gently toss until mixed. Taste and adjust seasoning with salt and pepper. Place in a serving bowl, sprinkle with Parmesan and serve.

Grilled Potatoes with Basil Mustard Vinaigrette…It’s what’s for a Side Dish.
Lovely. My husband hates vinegar, so i could never make this for just the two of us, but maybe next time we have company! I have grilled potatoes with pesto, though, and the flavor is magnificent!
Any kind of dish with potatoes will automatically be my favorite! This looks amazing!
I’m with you Cathleen! 🙂
Lea Ann,
That is such great news about Tony’s – I too love their stores. Congratulations!!!
Thank you Carol. I’m feeling quite special about the whole thing. 🙂
i am imagining these cold as a salad-side.
oh believe me, I ate them cold and they were just as good.
Congratulations Ms Ambassador! These look scrumptious!
Thank you Barb! 🙂
Recipe looks awesome. I’m always up for more basil in my life. We have a Tony’s of sorts in Salt Lake City. Tony Caputo’s Market and I love that place with all my heart also!!!
Great post!
You’ve mentioned that before RMW. And yay for those markets!
Hi Lea Ann, I lived in California most of my life but my mom was from Missouri, I love my potatoes. Beautiful recipe!
Thank you so much Cheri.
Any new way to make potatoes and I’m interested! These would be terrific with a grilled steak. I’ve made roasted potatoes with Dijon mustard and olive oil and they were great but the basil vinaigrette sounds like a wonderful addition.
I think it would be easy to make your own mustard basil vinaigrette. I had one at a cooking class with potatoes and the mustard was too overwhelming. I was going to try to make my own and adjust … then I found this wonderful little bottle of goodness.
Wow! These potatoes look awesome. I haven’t been to Tony’s in such a long time. Guess I better get over there!
As newly appointed ambassador, this is what I have to say “get over there!” 🙂
That sauce sounds delicious, especially on grilled red potatoes! What fun to be an ambassador to that cook market.
Oops- I meant to type cool market. Cook market works too, though. ?
I usually make my own vinaigrettes but this one will be on my regular shopping list. Next up, grilled chicken.
Tony chose a great ambassador when he picked you Lea Ann. These grilled potatoes look over-the-top delicious.

Thank you Sam.
I am going to Tony’s tomorrow and getting this marinade! Sounds amazing. Thanks Lea Ann!
Yay! I have no doubt you’ll be pleased. Flavor is perfect.
We love to par boil then grill potatoes, but never thought of using a vinaigrette – this sounds delicious.
I’ve even started par boiling when I stove top fry. My mom never did however.
Looks delish! Something to make with all the potatoes that will be coming out of my ears when I pull my garden in the next couple of weeks! Gotta love Tony’s Meats!
I love Tony’s.
And wouldn’t you know, roasted potatoes might just be one of my favorite sides. I’m a Midwesterner through and through. Love it, Lea Ann!
I think I had potatoes every single day growing up. I’m with you Sara.
