Posted by Niel Neethling on April 16, 2025

This garlic mushroom and tomato tart feels fancy but is easy to make. With earthy mushrooms, sweet tomatoes, and a creamy filling in a flaky crust, it’s perfect for a cozy dinner or brunch.

Ingredients

For the Crust:

1 1/4 cups all-purposeව
1/2 cup cold butter, cubed
1/4 tsp salt
3-4 tbsp ice water

For the Filling:

8 oz mushrooms (cremini, shiitake, or portobello), sliced
1 small onion, thinly sliced
2-3 garlic cloves, minced
1 cup heavy cream
2 large eggs
1 tsp fresh thyme or rosemary, chopped
1-2 ripe tomatoes, thinly sliced
1/2 cup shredded cheese (gruyère or cheddar, optional)
2 tbsp olive oil
Salt and pepper to taste

Step-by-Step Instructions

Step 1: Make the Crust

Mix flour and salt. Cut in cold butter until crumbly. Add ice water, 1 tbsp at a time, until dough forms. Shape into a disc, wrap, and chill for 30 minutes.

Step 2: Prep the Veggies

Heat 1 tbsp olive oil in a skillet over medium heat. Cook mushrooms for 5-7 minutes until golden. Season and set aside. In the same pan, add 1 tbsp oil and cook onions for 15 minutes until caramelized. Add garlic for the last minute. Cool slightly.

Step 3: Roll Out the Dough

Preheat oven to 350°F (175°C). Roll out dough to fit a 9-inch tart pan. Press into pan, trim excess, and prick bottom with a fork. Line with parchment and pie weights (or dry beans). Bake for 15 minutes, remove weights, and bake 5 more minutes.

Step 4: Make the Filling

Whisk eggs, cream, thyme or rosemary, salt, and pepper until smooth.

Step 5: Assemble the Tart

Spread mushrooms, onions, and garlic over the crust. Pour egg-cream mixture over, shaking gently to settle. Arrange tomato slices on top and sprinkle with cheese if using.

Step 6: Bake

Bake for 35-40 minutes until the filling is set with a slight wobble. Cool for 5-10 minutes before slicing.

Serving Suggestions

Serve warm or at room temperature with a green salad and vinaigrette.
Pair with a chilled Sauvignon Blanc.
Drizzle with herb-infused olive oil for extra flavor.

Tips and Storage

Use a mix of mushrooms (cremini, shiitake, portobello) for depth.
Store leftovers covered in the fridge for up to 3 days. Reheat in the oven.
Discard if the filling becomes watery or smells off.
