Wholesome Ingredients for This Rhubarb Breakfast Crisp

What makes this easy rhubarb crisp recipe so nutritious? Let’s take a closer look at some of its key ingredients:

Rhubarb: This vibrant vegetable is low in calories but high in fiber and antioxidants. For best results, use fresh rhubarb when in season, or frozen rhubarb during off months. Always discard the leaves, as they’re inedible.
Apples: We love Fuji or Rome apples in this recipe for their natural sweetness and crisp texture. If you’d like a slightly tarter flavor, swap in Granny Smith apples.
Maple syrup: A wholesome alternative to refined sugar, maple syrup adds a touch of natural sweetness along with minerals like zinc and manganese.
Granola: Whether you use homemade or store-bought, choose a granola with minimal added sugars and simple, whole-food ingredients. You could even go for a nut-free or keto-friendly version based on your dietary needs.

Ingredients for Rhubarb Breakfast Crisp

Grapeseed oil, for pan
1/2 cup plus 1/3 cup unsweetened applesauce
2/3 cup maple syrup
1 teaspoon fresh lemon juice
1 1/2 tablespoons tapioca starch
1/2 teaspoon ground cinnamon
6 rhubarb stalks, sliced 1/4 inch thick
2 Fuji or Rome apples, peeled, cored, and chopped
1 cup organic granola, homemade or store-bought

Step-by-Step Instructions

Preheat your oven to 350°F. Lightly grease a 9-inch pie dish with grapeseed oil and set aside.
In a large mixing bowl, whisk together 1/2 cup of unsweetened applesauce, maple syrup, lemon juice, tapioca starch, and ground cinnamon until smooth.
Add the sliced rhubarb and chopped apples to the bowl, tossing gently to coat the fruit evenly with the mixture.
Transfer the fruit mixture into the prepared pie dish, spreading it into an even layer. Cover loosely with foil and place the dish on a baking sheet to catch any bubbling juices.
Bake the fruit base in the preheated oven for 30 to 35 minutes, or until it’s hot and bubbly.
While the fruit bakes, combine the granola and remaining 1/3 cup applesauce in a small mixing bowl. Stir until the granola is evenly moistened.
Remove the foil from the baking dish and sprinkle the granola mixture evenly over the top of the fruit.
Return the dish to the oven and bake uncovered for an additional 12 minutes, or until the granola topping is lightly golden and crisp.
Let the crisp cool for at least 5 minutes before serving. Enjoy it warm or at room temperature!
