Peach & Blueberry Crunch with Steel-Cut Oat Crust

Nothing is better than a sweet, juicy ripe peach in the summertime. I combined steel-cut oats in a crust and topping with two of my favorite summer fruits–peaches and blueberries–for a quick and easy “crunch-type” dessert.Peach & Blueberry Crunch - IMG_4044

Another quick, easy and healthy dessert

The recipe uses a few simple healthy ingredients: quick cooking steel-cut oats, blueberries and fresh peaches. The blueberries are full of phytonutrients, especially anthocyanins–the colorful flavanoid pigments–which have antioxidant and anti-inflammatory properties. Peaches have carotene (Vitamin A- precursor) and both fruits contain fiber, Vitamin C and trace minerals. The oats have soluble fiber which helps lower cholesterol and regulate blood sugar. This nutritious “dessert” also makes a good breakfast and snack food, especially paired with yogurt.Ingredients - IMG_3972

Summer Peaches

Nothing is better than sweet, juicy and ripe peaches. I love their aroma and flavor. Fresh peaches are available in our groceries and farmer markets for a few months in the summer. To find the “perfect” peach a person has to be a little patient and tenacious–unless you have peach tree close to you.Peaches in Bowl - IMG_6356_1

Peaches are a “stone” fruit and can be picked before fully ripened. So the peaches are picked and shipped to grocery markets while still green and hard has a rock. The secret to great tasting peaches is to let them set on a kitchen counter or table (out of direct sunlight), stem side down, for several days while they continue to ripen and soften. Then use the peaches in recipes and eat while they are aromatic, soft and juicy.

To speed things up even more, place the peaches in a paper bag along with a banana. The banana and peaches put out ethylene gas which leads to the ripening.

Watch the peaches daily–they go from ripe to rotten quickly. But even over-ripe peaches can be cooked in desserts, pies, salsas and chutneys.

There are many varieties of peaches–classified as freestones and clingstones. Freestones separate easily from the pit and are best for eating. Clingstones cling to the pit and are good for canning. I purchase the same variety year after year from our neighborhood grocery store and consistently get a good quality. So find a reliable farmer’s market or grocery store.

My favorite are White Flesh Peaches. They are less acidic and sweeter (but are not so great for cooking as they fall apart when cooked). They have a wonderful flavor; a fuzzy peel and are best when sliced and eaten raw.

Peaches don’t grow well in southern Louisiana. The peach trees need a dormant period and it’s not cold enough here. Peaches do grow in Northern Louisiana. I stopped on a trip recently at Ruston, Louisiana, and purchased some Louisiana peaches. They were great.


We still have local blueberries at my neighborhood farmer’s market. So I combined a pint of blueberries with 2 cups of diced peaches for the filling. This combination of equal parts worked well in this recipe. For this version, I peeled the peaches; but if you are using really ripe peaches this probably isn’t necessary.Peach and Blueberries for the filling - IMG_4002

Steel-Cut Oats

I discovered steel-cut oats by accident; purchasing them by mistake when searching for quick-cooking oatmeal. They have become a family favorite, adding a nutty, crunchy taste to recipes. The steel-cut oats are finer in texture than oatmeal. When used in a crust and topping, they are crunchy but not as chewy as oatmeal which my family really liked.

Making the Recipe

This recipe is easy to make. I made it several times and finally came up with a version that seemed to have everything balanced. The steel-cut oats, flour, sugar, and a little salt are combined with the margarine. Cut in the margarine with a fork until the size of small peas. Almost there in this photo.Combining margarine with dry ingredients - IMG_4005This is divided between the crust and topping–two cups for the crust and one cup for the topping. Press the dough into an oiled casserole dish.

Then combine the peaches and blueberries with some sugar and cornstarch and stir to mix. This is poured over the crust and the topping is sprinkled over all.Crunch ready to bake - IMG_4008

Then bake until bubbly with a browned crust! That’s it. The blueberries and peaches may not taste completely cooked. That’s okay.
