Preheat your oven to 400 degrees Fahrenheit. Arrange the baguette slices in a single layer on a large baking sheet and brush both sides lightly with extra virgin olive oil. Bake for about 8 to 10 minutes, turning halfway through, until the edges are golden brown and the bread is crisp. Remove them from the oven and let them cool slightly so they stay crunchy when topped.
In a small microwave-safe bowl or a tiny saucepan over low heat, combine the honey and the red pepper flakes. Heat the mixture for about 30 seconds in the microwave or 2 minutes on the stove until the honey is thin and runny. Let it sit for at least 5 to 10 minutes to allow the spice from the peppers to infuse into the honey. If you prefer a smoother texture, you can strain the flakes out before serving, but I like the look of the red flecks for Christmas.
Place the crumbled feta, Greek yogurt, lemon juice, and minced garlic into a food processor or high-speed blender. Process the mixture on high for 1 to 2 minutes until it is completely smooth and airy. Stop to scrape down the sides of the bowl as needed to ensure no large chunks of feta remain. Taste the mixture and add a pinch of black pepper if desired, though the feta usually provides enough saltiness.
Spread a generous tablespoon of the whipped feta onto each toasted crostini slice. Drizzle a small amount of the prepared hot honey over the top of the cheese. Finish each piece with a few fresh thyme leaves and a scattering of pomegranate seeds to give it that festive Christmas sparkle. Arrange them on a wooden serving board or a holiday platter and serve immediately.
