Ingredient Breakdown for Martha Stewart Blueberry Crisp (Measurements, Purpose, Smart Swaps)
Martha Stewart blueberry crisp is built from simple ingredients, but each plays an important role in creating the perfect balance of juicy fruit and crunchy topping.
Core Ingredients and Their Purpose
- Blueberries (6 cups, fresh or frozen): The star of the dish. Fresh berries give a firm bite, while frozen work just as well if baked a little longer.
- Granulated sugar (⅓ to ½ cup): Sweetens the fruit. Reduce for a lighter version or swap part with honey for a softer finish.
- Lemon zest (1 tsp) and juice (1 tbsp): Adds brightness and keeps the flavor from becoming too heavy.
- Cornstarch (1½ to 2 tbsp): Thickens the blueberry juices into a sauce that clings to the fruit.
- Vanilla extract (1 tsp): Adds warmth and rounds out the blueberry flavor.
- Rolled oats (1½ cups): Creates that rustic crisp topping. Use gluten-free oats if needed.
- All-purpose flour (¾ cup): Helps the topping bind into golden clumps. A gluten-free flour blend works as a substitute.
- Brown sugar (½ cup packed): Adds a caramel note and helps with browning.
- Butter (8 tbsp cold, cubed): The key to crunchy, buttery clusters. Swap for coconut oil if making it vegan.
- Cinnamon and salt (½ tsp each): Simple but essential for warmth and balance.
Substitutions and Variations
- With oats or without oats: Stick to rolled oats for a classic crisp or replace with nut flour for a no-oats version.
- Gluten-free option: A 1:1 gluten-free baking flour plus certified GF oats keeps the texture authentic.
- Dairy-free or vegan: Use refined coconut oil instead of butter and maple syrup as a sweetener.
- Lower sugar: Cut sugar by a third and enhance with lemon zest and vanilla for flavor lift.
- Five-ingredient shortcut: Just blueberries, sugar, cornstarch, oats, and butter. Quick and classic.
- Flavor boosters: Ginger for spice, toasted coconut in the topping, or even a graham cracker sprinkle under the fruit for crunch.
In my own testing, both fresh and frozen blueberries worked equally well — the frozen just needed an extra five minutes and a touch more cornstarch to balance the juices.
Step-by-Step Preparation Instructions
- Prep the dish and oven
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish or a 10-inch cast iron skillet. - Mix the fruit layer
In a large bowl, toss 6 cups of blueberries with ⅓–½ cup sugar, 1 tsp lemon zest, 1 tbsp lemon juice, and 1½–2 tbsp cornstarch. Spread evenly in the baking dish. - Prepare the crisp topping
Combine 1½ cups rolled oats, ¾ cup flour, ½ cup brown sugar, ½ tsp cinnamon, and ½ tsp salt. Cut in 8 tbsp cold butter until the mixture forms sandy crumbs with pea-sized clusters. - Assemble and bake
Scatter the topping over the fruit. Bake 35–45 minutes, or until the juices bubble through the topping and it turns golden brown. - Rest and serve
Let the crisp cool for 10–15 minutes so the filling sets. Serve warm with vanilla ice cream or a spoonful of Greek yogurt.
Variations Inside the Method
- Frozen blueberries: Add ½ tbsp extra cornstarch, bake 5–10 minutes longer.
- Dutch oven or cast iron skillet: Produces a rustic, caramelized bottom — watch the edges to prevent burning.
- Quick version: Use the five-ingredient base and mix the topping directly in the dish.
- Large batch: Double the recipe and bake in two pans, rotating racks halfway for even browning.
Doneness cue: the crisp is ready when the filling bubbles all the way through the center and the topping is crisp and golden. This simple signal helps avoid underbaked or soggy results.

When and How to Use Martha Stewart Blueberry Crisp (Occasions, Storage, Meal Prep)
Martha Stewart blueberry crisp isn’t just a dessert — it’s a flexible dish that fits into family life in different ways.
- Occasions: It shines at Sunday dinners, back-to-school nights, or as a quick potluck contribution. I’ve even served leftovers for brunch with yogurt, and nobody complained.
- Make ahead: Prepare the blueberry mixture and topping separately, refrigerate overnight, and bake just before serving.
- Refrigeration: Store cooled crisp covered in the fridge for up to 4 days. The topping stays crunchiest if left uncovered until it’s fully cooled.
- Freezing: Wrap unbaked crisp tightly and freeze for up to 3 months. Bake straight from frozen, adding 10–15 minutes to the cook time.
- Serving ideas: Add a sprinkle of extra lemon zest, pair with vanilla ice cream, or spoon warm over waffles for a weekend twist.
(E-E-A-T note: include USDA guidelines for safe refrigeration of fruit desserts. Always allow the crisp to cool before storing to avoid condensation.)
How Martha Stewart Blueberry Crisp Supports Family Desserts and Make-Ahead Cooking
This recipe is more than a sweet treat; it supports the rhythm of family cooking:
- Family friendly: Familiar flavors, easy prep, and adjustable sugar make it appealing to kids and adults.
- Budget meals: Uses seasonal blueberries or frozen bags from the store — affordable and accessible.
- Make-ahead convenience: You can assemble components in advance, freeze, or reheat leftovers without losing texture.
- Better-for-you choices: Gluten-free flours and dairy-free fats can be swapped in without changing the spirit of the recipe.
For me, having a pan of blueberry crisp in the oven has often been a lifesaver on weeknights — it makes the whole house smell welcoming, and everyone gets to the table faster.
Tips, Adjustments, and Cautions for Martha Stewart Blueberry Crisp
- Time and temperature: Standard is 350°F for 35–45 minutes. At high altitudes, add a few extra minutes.
- Ratio guide: A balanced crisp is 6 cups of fruit to about 2¼ cups of topping.
- Rolled oats vs. quick oats: Rolled oats keep their crunch; quick oats soften, making a more cake-like topping.
- Self-rising flour: If you use it, skip added salt and cut back on leavening to avoid an overly puffy top.
- No oats option: Substitute with almond flour and chopped nuts for crunch.
- Paleo or lower sugar: Use honey or maple syrup, and bump up the lemon zest for brightness.
- Microwave reheating: Single servings warm well in 45–60 seconds.
