The Recipe How-To

Step 1: Preheat the oven

Preheat your oven to 375°F.

Step 2: Prep the tart crust

Start with a store-bought pie crust or puff pastry, or make your own unsweetened pastry. Roll it out to fit a 9-inch tart pan, and use a fork to prick it all over.

Tip: To avoid a soggy crust, brush it with a beaten egg before adding the filling.

Step 3: Add the mustard and seasonings

Spread 3-4 tablespoons of French mustard (Dijon mustard will work well too) over the base of the tart crust. Sprinkle 1 teaspoon of dried oregano and 2 teaspoons of dried basil or Herbs de Provence.

Tip: Use leftover roasted garlic for extra flavor.

Step 4: Layer cheese and tomatoes

Place 6 slices of Swiss cheese, 1/4 inch thick, on top of the mustard. Arrange 3 large ripe tomatoes, thinly sliced, in a single layer on top of the cheese.

Tip: Use any cheese you like. Try shredded Gruyere or Swiss cheese for different flavors.

Step 5: Add finishing touches

Drizzle with 1 tablespoon olive oil, season with freshly ground black pepper, and sprinkle with grated Parmesan cheese if you like.

Tip: Add fresh basil leaves for added flavor and a pop of color.

Step 6: Bake until golden brown

Bake for about 35-40 minutes, or until the tart is nicely golden brown around the edges and the cheese is melted and bubbly.

Tip: For a crispier crust, place the baking dish on a heated baking sheet in the oven.

Step 7: Cool and serve

Let cool for at least 10 minutes before slicing and serving. This delicious French Tomato Mustard Pie can be served hot, warm or cold!

Variation:* Make it fancy by garnishing with a drizzle of balsamic glaze or sprinkling sliced cherry tomatoes on top before baking.

And there you have it, an easy-to-follow recipe for French Tomato Mustard Pie that’s classic French cooking at its best!

Substitutions and Variations

Looking to put your own spin on this classic French tomato mustard pie recipe? There are plenty of variations and substitutions that you can make to give it a unique twist.

For the crust, you can use puff pastry instead of the classic French pie crust. This will add a flakiness and lightness that complement the savory flavors of the filling. Or if you prefer a crumbly and crunchy crust, try using a graham cracker or bread crumb base instead.

If you’re not a fan of Swiss cheese, substitute it with something equally as flavorful, like Gruyere or Parmesan. Goat cheese also works well in this recipe and adds a tangy texture to the savory filling. You can either mix goat cheese into the filling or sprinkle it on top during the last few minutes of baking.

For the tomatoes, experiment with different varieties such as cherry tomatoes or colorful heirloom tomatoes to add visual appeal and depth of flavor. If using cherry tomatoes, you can either halve them or leave them whole for smaller bites.

Looking for more spice? Add a pinch of red pepper flakes to your tomato mustard mixture for some heat. You can also swap out French mustard with spicy Dijon mustard for an added kick.

Lastly, fresh herbs like oregano or basil can be added to the filling mixture for even more flavor. Or try using herbes de Provence, which is a blend of herbs commonly found in French cooking that will impart an earthy aroma to your dish.

No matter what substitutions or variations you choose, this versatile recipe is sure to impress and satisfy your taste buds.

Tips for Perfect Results

To ensure your French tomato mustard pie comes out perfectly every time, follow these helpful tips:

Firstly, make sure you slice your tomatoes very thinly. This is important to ensure they cook evenly and do not release too much moisture onto the crust. A good rule of thumb is to slice them no thicker than 1/4 inch.

It’s also crucial to use a high-quality French mustard. This adds a unique tangy flavor that pairs perfectly with the sweetness of the ripe tomatoes. I recommend using Dijon mustard or a grainy brown mustard for the best taste.

When it comes to cheese, Swiss cheese works best for this recipe as its mild flavor complements the other ingredients without overpowering them. Be sure to shred your Swiss cheese finely for optimal melting and distribution throughout the pie.

Prior to assembling your pie, sprinkle some grated Parmesan cheese on top of the prepared crust. This will help create a barrier between the crust and any excess liquid from the tomatoes.

For an extra burst of flavor, sprinkle some fresh herbs such as oregano or basil over the top of the pie before popping it in the oven.

Finally, make sure to let your pie cool down for at least 10-15 minutes before slicing it to ensure it holds together properly. And most importantly, enjoy!
