Steps
Before you start
- Slice the sourdough loaf to ¼-inch (6 mm) thickness so it toasts evenly without burning
- Remove the brie from the refrigerator 15 minutes before assembling so it softens slightly
- Have all ingredients measured and the oven preheated to 400°F (200°C) before you begin
Mix butter and thyme
- In a small bowl, combine the softened butter with the chopped fresh thyme and a pinch of sea salt.
- Stir until well blended and the thyme is evenly distributed throughout.

Ready when: Thyme is evenly blended into the butter
Tip: Make sure the butter is truly softened (yielding to gentle pressure) so the thyme distributes evenly without breaking apart the leaves.
Preheat oven and arrange breadOven 400°F / 205°C
- Preheat your oven to 400°F (200°C).
- Arrange the sourdough slices in a single layer on a large baking sheet, cutting them in half if necessary to fit.

Tip: Use day-old or slightly stale sourdough—it holds up better to toasting and won't fall apart under the toppings.
Brush bread with thyme butter
- Using the back of a spoon or a pastry brush, spread a thin, even layer of the thyme butter onto the top side of each bread slice.
- Use about ½ teaspoon per slice.

Ready when: All slices are evenly coated with a light layer of thyme butter
Tip: Don't oversaturate the bread; a thin coating is enough to add flavor and help toast evenly. Excess butter can burn.
Toast bread until crispOven 400°F / 205°C
- Place the baking sheet in the preheated 400°F (200°C) oven and toast for 5–6 minutes, until the bread is golden brown and the edges are crispy but the centers still have some give.

Ready when: Bread is golden brown on top with slightly darker, crispy edges
Tip: Watch the toasts from 4 minutes onward—oven temperatures vary, and sourdough can brown quickly once it starts coloring.
Top with brieOven 400°F / 205°C
- Remove the baking sheet from the oven and quickly place a slice of brie on each warm toast.
- Return the sheet to the oven for 2–3 minutes, until the brie is softened and beginning to melt but still holds its shape.

Ready when: Brie surface shows a slight sheen and gently yields to light pressure
Tip: The brie should melt just enough to soften but not collapse completely—it will continue to warm as you work. Timing is quick, so keep an eye on it.
Add cranberry jam and finish
- Remove the tartines from the oven and place on a serving platter.
- While the brie is still warm, spoon a small dollop (about ½ teaspoon) of cranberry jam onto the center of each slice.
- Top with a fresh thyme sprig if using, and a small crack of black pepper.
- Serve within 2 minutes while the bread is still crispy and the brie is warm.

Ready when: Jam is distributed, garnishes are in place, and tartines are ready to serve
Tip: The contrast of warm melted brie, tart jam, and crispy toast is best enjoyed immediately, so assemble this final step just before serving.
Good to know
Tips
- Slice the brie by briefly freezing it for 15 minutes first—it cuts more cleanly and evenly without crumbling or tearing.
- For a crowd, slice the brie into portions before heating and layer them on the toast for more even melting.
- If the bread feels too soft when you slice it, toast it lightly on a skillet or under a broiler for 2–3 minutes before buttering to firm it up.
- Serve these on small appetizer plates or a wooden platter lined with parchment for an elegant presentation.
Make ahead
You can prepare the thyme butter and slice the bread up to 4 hours ahead. Wrap the bread tightly to keep it from drying out further. Toast the bread and assemble the tartines no more than 15 minutes before serving for the best texture and temperature contrast.
Storage & reheating
These tartines are best enjoyed immediately. Leftover baked toasts (without toppings) can be stored in an airtight container at room temperature for up to 2 days and re-crisped in a 350°F (175°C) oven for 3–4 minutes. Do not refrigerate assembled tartines, as the brie will harden and the bread will become chewy.
Substitutions
- cranberry jam (or whole-berry cranberry sauce) → fig jam or apricot jam. Both offer similar sweet-tart balance and pair beautifully with brie. Use the same quantity.
- brie cheese, wheel or wedge → camembert or other soft-ripened cheese. Camembert melts slightly slower but offers a richer, more mushroom-forward flavor. Adjust melting time by 1 minute if needed.
- fresh thyme leaves → fresh rosemary (chopped) or herbes de Provence. Rosemary is more robust; use just 1 teaspoon. Herbes de Provence (1 teaspoon) brings a Provençal twist.
- sourdough loaf, day-old or slightly stale → multigrain or whole-wheat sourdough loaf. Adds a nuttier, earthier flavor and complements the brie and jam equally well. May require 1 extra minute of toasting.
