Living in Arkansas this spring, it’s nice to see fresh produce arriving sooner in the season. In New Hampshire, rhubarb typically appears in late April or May. Here, I’ve had access to it since late March. Although there are things about New Hampshire I miss, the colder weather and lesser amounts of produce aren’t among them.

When I spied rhubarb at the grocery store, I knew that I wanted to do two things. One, begin a series on spring ingredients. Every year the return of spring is exciting. This year embracing spring and its new growth seems even more important. Second, continue to promote rhubarb as an ingredient to be used in savory dishes.

Over the years, I’ve made a number of savory items with rhubarb, which will be highlighted later this week. For today I want to focus on this roasted rhubarb & ricotta flatbread. It’s a really simple dish, especially if you’re comfortable making your own pizza dough. If the prospect of yeast concerns you, cut a corner. I won’t judge. Buy pre-made crust in whatever variety pleases you.

Now, onto the toppings: rhubarb, onions, and ricotta. The hardest one isn’t even hard; it’s simply a matter of patience. Caramelizing the onions will take about 15 minutes, but it requires little more than occasionally stirring. The rhubarb simply needs to be sliced and roasted. The ricotta has to be whisked.

Finally, assemble and bake. So, you either need to roll out dough or take the pre-formed crust out of its package. Top with ingredients. Bake. See? It’s easy.

When it’s done you have a pizza that may be the most unique you’ve ever had. In this case unique is also amazing! Creamy ricotta, sweet and savory onions, and tangy rhubarb make a combination of amazing flavors and textures to enjoy.

If you have leftover rhubarb, this rhubarb salsa is an excellent way to use it.
