Instructions

Prepare the Mushrooms:
Heat olive oil in a wide non stick frying pan over medium heat until shimmering Add the crushed garlic and sauté gently for about one minute stirring the whole time to avoid burning Toss in the sliced mushrooms and pour in the tamari sauce Cook for eight to ten minutes stirring occasionally until the mushrooms give off their moisture and become deeply tender Stir in thyme leaves and finish with several twists of black pepper to taste

I am obsessed with thyme in this recipe because it brightens up the deep mushroom flavor. The first time I watched my family pass around their toast and argue over the biggest slice I knew I had a new brunch crowd pleaser.

Storage Tips

store any leftover mushrooms in a sealed container in the fridge up to three days. avocado mash is best fresh but you can press plastic wrap to the surface to keep it green for a few extra hours. for meal prep keep each layer separate and assemble just before eating to keep toast crisp.

Ingredient Substitutions

if you cannot find chestnut mushrooms swap in cremini or button mushrooms. soy sauce works in place of tamari if gluten is not a concern. no thyme on hand try chopped chives parsley or a dash of dried Italian herbs. use your favorite hearty bread from multigrain to rye.

Serving Suggestions

top off with a sprinkle of chili flakes or a swirl of your favorite hot sauce for a kick. add thinly sliced radish or arugula for a peppery bite. serve with a side of fresh fruit or roasted sweet potatoes for a filling brunch plate.

Making It Through the Seasons

in winter swap thyme for rosemary and add a little grated Parmesan over the mushrooms. in summer add sliced tomato or grilled zucchini right on top. when mushrooms are out of season try sautéing thinly sliced leeks instead. The toasty bread base keeps it satisfying any time of year.

Success Stories

my kids ask for this every weekend and even enjoy piling on extra mushrooms. a friend tried it with gluten free bread and said it was the first breakfast toast that actually felt indulgent. perfect for brunch gatherings because everyone can personalize their own slice.

Freezer Meal Conversion

while assembled avocado toast does not freeze well you can freeze the cooked mushrooms in a container for up to one month. defrost overnight in the fridge reheat in a pan and use on fresh toast with avocado. great to prep the mushroom topping whenever mushrooms are in season and plentiful.
