Hi there, I’m Sienna Hartwell, and I’m so incredibly happy to welcome you to The Cook Chic! This little corner of the internet is more than just a recipe blog to me; it’s a heartfelt extension of my kitchen, a place where I get to share the joy, comfort, and creativity that cooking has brought into my life for as long as I can remember. At 37, launching this has been a dream come true, a way to pass on the culinary love that was so generously gifted to me.
It all began with a secret, and a very special neighbor. For me, it wasn’t in a bustling professional kitchen or a formal culinary school. It started when I was thirteen, right here in Canada, in the most wonderfully fragrant and welcoming place imaginable: the kitchen of my elderly neighbor. She was a remarkable woman, seventy years young, with a twinkle in her eye and a collection of “secret recipes” that felt like pure magic to my teenage self.
Now, at 37, The Cook Chic is my way of paying forward that incredible gift. It’s about sharing those precious heirloom recipes and the new favorites I’ve gathered. Today, I’m so excited to share one of my go-to recipes for those casual summer evenings: Grilled Portobello Mushroom Burgers. These are my absolute favorite for a veggie BBQ option!
They’re incredibly easy to make and packed with so much flavor. Honestly, even meat lovers rave about them. It’s a simple recipe, but it feels special. Let’s get grilling!

Crafting the Perfect Grilled Portobello Mushroom Burgers (Veggie BBQ Option)

First, get your grill ready. You want it at a nice medium heat. While it’s heating up, grab that small bowl we talked about. Whisk together the olive oil, minced garlic, balsamic vinegar, dried thyme, salt, and pepper. This is your flavor booster!
Next, take your portobello mushrooms and give both sides a good brush with that lovely marinade. Make sure they’re well coated so they soak up all that goodness.
Carefully place the marinated mushrooms on your preheated grill. Let them cook for about 5 to 7 minutes on each side. You’ll know they’re ready when they’re tender and have those nice grill marks.
While the mushrooms are doing their thing, you can quickly toast your burger buns on the grill if you like. I always do; it adds a little extra something.

Ingredient Notes and Substitutions
One of the things I love about cooking is how flexible recipes can be! These grilled portobello mushroom burgers are no exception. You can easily switch things up based on what you have or what you like.
If you don’t have balsamic vinegar, red wine vinegar works too. Feel free to swap out the thyme for other dried herbs like oregano or rosemary. You could even add a pinch of smoked paprika for a little extra depth! Don’t be afraid to experiment a little.

I often get asked a few questions about making these grilled portobello mushroom burgers, so I thought I’d answer them here!
Can I cook these indoors? Absolutely! You can easily cook them in a grill pan on your stovetop if the weather isn’t cooperating or you don’t have an outdoor grill.
How long do leftovers last? If you happen to have any leftovers, they’ll keep in the fridge for about 3-4 days in an airtight container. They’re great reheated!
Can I add cheese while grilling? Yes, you totally can! Towards the end of the grilling time, just pop a slice of your favorite cheese on top of the mushroom. It melts beautifully.
Hope these help you make the best burgers!
