Ingredients

This recipe focuses on efficiency without compromising that beloved lemon meringue flavor. We’ll group the ingredients to make assembly even smoother.

For the Lemon Filling:

• 1 baked pie crust (your favorite store-bought or homemade, blind-baked to perfection)
• 1 ¾ cups sugar, divided (6 tablespoons will be reserved for the meringue)
• ½ cup cornstarch
• ¼ teaspoon salt
• 1 ½ cups water

• ½ cup lemon juice (freshly squeezed from about 2 medium lemons)
• 2 teaspoons fresh lemon rind, finely grated (from about 1 medium lemon)
• 2 tablespoons butter, unsalted

For the Meringue:

• 3 large egg whites (ensure they are at room temperature for best volume)
• 6 tablespoons sugar (this is the portion of the total sugar you set aside)
• ¼ teaspoon salt

Equipment Needed

To bring this speedy pie to life, you’ll want to have these on hand:

• A microwavable bowl (at least 2-quart capacity)
• A whisk
• A measuring cup and spoons
• A citrus juicer and grater
• A medium bowl for tempering eggs
• A food processor (or electric mixer for the meringue)
• A pie dish (9-inch standard pie plate)
• An oven

Instructions

The magic of this recipe lies in its streamlined approach. We’ll conquer the lemon filling in the microwave and then tackle the glorious meringue.

1. Prepare the Filling Base: In your microwavable bowl, combine the sugar (minus the 6 tablespoons reserved for the meringue), cornstarch, and salt. Whisk these dry ingredients together thoroughly to break up any lumps of cornstarch.
2. Add Water and Initial Microwave Cook: Gradually whisk in the water until the mixture is smooth. Place the bowl in the microwave and cook on high power for 5 minutes.
3. First Stir and Check Consistency: Carefully remove the bowl from the microwave (it will be hot!). Stir the mixture once. It should be starting to thicken and become more transparent.
4. Temper the Egg Yolks: While the filling mixture is cooking or cooling slightly, prepare to temper your egg yolks. In a separate medium bowl, lightly beat the egg yolks. To temper them, very gradually whisk about ½ cup of the hot lemon mixture into the beaten egg yolks. This gentle warming process prevents the yolks from scrambling when added to the hot filling.
5. Incorporate Lemon Flavor: Whisk the tempered egg yolks back into the hot lemon mixture in the microwavable bowl. Add the lemon juice and lemon rind. Stir everything together until well combined.
6. Second Microwave Cook: Return the bowl to the microwave and cook on 70% power for 3 minutes. Stir well after this cooking period. The filling should now be beautifully thickened and glossy.
7. Add Butter and Pour: Remove the filling from the microwave. Stir in the butter until it is completely melted and incorporated, adding a lovely richness. Immediately pour the hot lemon filling into your pre-baked pie crust.
8. Chill the Filling: Allow the filling to cool slightly at room temperature, then refrigerate the pie for at least 30 minutes to allow it to set further before adding the meringue. This helps prevent the meringue from sinking.
9. Prepare the Meringue: While the filling is chilling, prepare the meringue. In the bowl of a food processor, combine the egg whites, the reserved 6 tablespoons of sugar, and ¼ teaspoon salt. Process or beat on high speed until stiff peaks form. The sugar should be completely dissolved into the egg whites, creating a glossy, smooth meringue. You can test this by rubbing a little between your fingers – it shouldn’t feel gritty.
10. Top the Pie: Spoon the meringue over the chilled lemon filling, ensuring it touches the edges of the crust all around to prevent shrinking. Create decorative swirls or peaks with your spoon or spatula.
11. Bake the Meringue: Preheat your oven to 350°F (175°C). Place the pie on a baking sheet (to catch any potential drips) and bake for 10 to 12 minutes, or until the meringue is a beautiful golden brown.
12. Cool and Serve: Remove the pie from the oven and let it cool completely on a wire rack before slicing and serving. This cooling period is crucial for the meringue to set properly.

Expert Tips & Tricks

• Room Temperature Egg Whites: For the fluffiest meringue, always use room temperature egg whites. They whip up to a greater volume than cold egg whites. If you forget to take them out in advance, place them in a bowl and cover with warm (not hot) water for about 5-10 minutes.
• Microwave Wattage Matters: Microwave ovens vary in power. If your microwave is a lower wattage, you might need to add an extra minute or so to the initial cooking time for the filling. The key is a thick, transparent consistency.
• Lemon Juice Freshness: While bottled lemon juice can be used in a pinch, the flavor of fresh lemon juice is unparalleled and truly elevates this pie. It’s worth the extra step of squeezing your own.
• Preventing a Weeping Meringue: A weeping meringue is often caused by undissolved sugar or overcooking. Ensure all the sugar is dissolved during the whipping process and avoid over-baking the meringue. The rapid cooling after baking can also contribute, so allow it to cool gradually.
• Blind-Baking is Key: For a crisp crust that doesn’t get soggy, ensure your pie crust is properly blind-baked before adding the filling. This involves baking the crust with pie weights or dried beans until it’s golden brown and firm.

Serving & Storage Suggestions

This lemon meringue pie is best served chilled or at cool room temperature. The contrast between the tangy, cool filling and the airy, sweet meringue is pure bliss. Slice it carefully with a sharp knife dipped in hot water for clean cuts.

Storage:

• Room Temperature: Leftover lemon meringue pie is best stored in the refrigerator due to the meringue. If left at room temperature, it should be consumed within 2 hours.
• Refrigeration: Store any leftovers loosely covered (to prevent the meringue from getting soggy) in the refrigerator for up to 3 days. The meringue may weep slightly over time.
• Freezing: Lemon meringue pie does not freeze well. The texture of the meringue can become watery and grainy upon thawing.

Variations & Substitutions

• Citrus Twist: While lemon is classic, you could experiment with other citrus fruits like lime or grapefruit for a different tang. A blend of lemon and lime is also delicious.
• Gluten-Free Crust: Use your favorite store-bought or homemade gluten-free pie crust recipe. Ensure it’s fully baked before adding the filling.
• Richness Boost: For an even richer filling, you could substitute some of the water with a dairy-free milk like coconut milk, or a small amount of heavy cream if not aiming for a dairy-free option.

FAQs

Q: Can I make the lemon filling ahead of time?
A: Yes, you can make the lemon filling and store it in an airtight container in the refrigerator for up to 2 days. You will need to reheat it gently before pouring it into the pie crust and topping with freshly made meringue.

Q: My meringue is weeping. What did I do wrong?
A: Meringue weeping can occur if the sugar isn’t fully dissolved, or if the meringue is overcooked or cooled too quickly. Ensure you beat the meringue until it’s smooth and glossy, and allow the pie to cool gradually.

Q: Can I use a pre-made meringue topping?
A: While you can, it won’t have the same fresh flavor and texture as homemade. Homemade meringue is quick to whip up and truly completes the pie experience.

Q: Is it really safe to cook egg yolks in the microwave?
A: Yes, it is safe when the yolks are tempered properly. Tempering slowly introduces the hot liquid to the yolks, raising their temperature gradually and preventing them from cooking into scrambled eggs.

Q: How do I know when the meringue is baked correctly?
A: The meringue is ready when it’s a beautiful golden brown color. The peaks should hold their shape, and the surface should feel slightly firm to the touch.

This fast microwave lemon meringue pie is a testament to how modern appliances can simplify even our most cherished culinary traditions. It’s a recipe that proves you don’t need hours to achieve a dessert that brings joy and bright, sunny flavor to your table. Enjoy every delightful, zesty bite!
