This Grilled Vegetable Marinade with lemon and thyme is the perfect marinade and basting sauce for summer! It’s also Paleo, Keto, low-carb and Whole30 compliant!
This is a do-over of one of my very first posts, Grilligan’s Island. I didn’t like my photos the first time, so now, 8 years later, I’ve re-done it.

Perfect for any diet or lifestyle
I’ve also made a minor change to this marinade to make this Paleo friendly and Whole30 compliant; simply substitute the butter for clarified butter or ghee. Make sure that you check your mustard if you are being really strict! If you’re following a low-carb or keto diet, you won’t need to change a thing!
Not interested in the dietary labels? It’s just another method to indicate that this is a simple and unprocessed recipe. The ingredients are just butter, olive oil, chopped shallots, mustard, lemon juice and fresh thyme, which makes it a healthy addition to any meal.
I love to make a large platter of these grilled vegetables for a big summer BBQ, but even if I make this amount, just for my family , they’ll end up eating twice as many vegetables when I serve them grilled with this amazing basting sauce. Seriously, what you don’t devour the first night is great the following day in an omelet or salad.
This marinade is perfect for a variety of vegetables!
While not low carb, sweet potatoes or corn on the cob would be great as well, (but not low-carb). If I purchase small mushrooms, I’ll skewer them, but this time, I found some really big brown mushrooms which I sliced. Big Portobello mushrooms would be fabulous too! Asparagus, mushrooms and the onions are everyone’s favorites.
I made this platter last week for dinner with some grilled chicken for my family of four. Of what you see here, all the mushrooms were eaten, (about a pound), all of the zucchini (2), one whole onion and nearly all of the bunch of asparagus.
We had leftover bell peppers and carrots and eggplant. (Spencer hates eggplant…I’m not really sure why I torture him with it!) I like to put the left-over grilled vegetables in sandwiches or in salads. The following night I ate a large plate of them with feta cheese for my dinner. These vegetables go well with Greek Grilled Chicken or Rosemary Shrimp.
This grilled vegetable marinade with lemon and thyme recipe comes from Bon Appetit, from about 1993?
