What You Need Before You Start
Before using your egg cuber, you’ll need a few simple things:
Ingredients:
-
Fresh eggs (large or medium size works best)
-
Cold water
-
Ice cubes (for cooling)
Tools:
-
Saucepan or egg boiler
-
Slotted spoon
-
Egg cuber
Optional tools for better results:
-
Timer (to ensure perfect boiling)
- Kitchen towel or gloves (for handling hot eggs)
Step-by-Step Guide: How to Use an Egg Cuber
Follow these easy steps to get the perfect cube-shaped egg every time:
Step 1: Boil the Eggs
-
Place your eggs in a saucepan and add enough water to cover them by about an inch.
-
Bring the water to a gentle boil.
-
Once boiling, reduce the heat and simmer for 10–12 minutes for fully hard-boiled eggs.
-
Use a slotted spoon to remove the eggs and place them immediately into cold water with ice cubes.
-
Let them cool for about 5 minutes before peeling.
Pro Tip: The eggs should still be slightly warm when placed in the cuber. Warm eggs are more flexible and take the cube shape better.
Step 2: Peel the Eggs Carefully
Gently peel the shells while the eggs are still slightly warm. Be sure not to tear the egg whites smooth surfaces create the best-looking square eggs.
If the shells are hard to remove, roll the egg lightly on a countertop to loosen them.
Step 3: Place the Egg in the Cuber
-
Open the egg cuber and place the peeled warm egg in the center of the mold.
- Position the top plate or lid over the egg.
Step 4: Tighten the Lid Gently
Slowly screw down or press the lid until you feel light pressure on the egg. Don’t over-tighten the egg could break or lose shape. You want a snug fit, not a squished one.
Step 5: Chill the Egg
Place the entire cuber (with the egg inside) into the refrigerator for 10–15 minutes. Cooling helps the egg hold its new square shape.
You can even leave it longer, about 30 minutes, for a firmer, more defined cube.
Step 6: Remove and Serve
Once cooled, open the cuber and carefully remove your perfectly square egg. It should have sharp edges and a clean cube shape.
Slice it, serve it whole, or use it creatively in meals.

Tips for Perfect Square Eggs Every Time
-
Use warm eggs: Cold eggs are too firm to mold properly.
-
Don’t rush cooling: Let the egg chill fully before removing the mold.
-
Avoid over-tightening: Gentle pressure prevents cracks.

Use large eggs: They fill the mold evenly for a perfect cube.
