Macaron Troubleshooting

While I’d love to think everyone’s first batch of French macarons will turn out perfectly, my own experience has taught me that’s not how things usually go. That’s why I’m sharing this macaron troubleshooting guide.

Macarons are incredibly temperamental, and it might take a few tries to get them just right.

It took me several batches to get them just right, with those perfect little feet and a smooth shiny top.

Below are some of the issues I’ve run into when baking macarons, along with ways to prevent them from happening again.

Macaron Troubleshooting Issue #1: Why Do My Macarons Have Cracked Shells?

Cracked shells were the first issue I ran into when I started baking macarons.

A few different things can cause cracked shells, including too short of a rest, trapped air bubbles, too hot of an oven, or under-mixed batter.

Potential Fixes: Bang your pans firmly before resting your macarons, rest your macarons until they form a skin, check your oven for hot spots, or mix your batter slightly more.

Macaron Troubleshooting Issue #2: Why Are My Macarons Hollow?

Hollow macarons have big air pockets between the top of the shell and the base. This can happen when the meringue or batter is undermixed or if air bubbles get trapped before being baking.

Potential Fixes: Make sure you’re not under mixing your meringue/batter, or bang your pans firmly against your counter before letting them rest.

Macaron Troubleshooting Issue #3: Why Are My Macarons Sticking to My Baking Sheet?

Your macarons may stick to your mat/parchment paper if they’re underbaked, or if you didn’t let them cool fully before trying to remove them.

Potential Fixes: Let your macarons fully cool before trying to lift them, or bake them slightly longer.

Macaron Troubleshooting Issue #4: Why Don’t My Macarons Have Feet?

If your macarons don’t develop feet, it could be because your batter is too wet, your batter was over-mixed or you didn’t let your macarons rest for long enough.

Potential Fixes: Try using aged egg whites, make sure you’re not using liquid flavoring / food coloring, or let you shells rest until they form a touchable skin (20-60 minutes).

Macaron Troubleshooting Issue #5: Why Are My Macarons Crispy/Hard?

Sometimes if your batter is overmixed it causes your shells to spread more and bake up crispy. They may also just be overbaked!

Keep in mind that macaron shells soften once they’re filled and have time to mature in the fridge. Don’t be disheartened if they seem a bit firm once they’ve cooled.

Potential Fixes: Mix your batter less, bake your macarons for less time, brush the bottoms with milk, or fill them and see if the maturation process softens them.

Macaron Troubleshooting Issue #6: Why Are My Macaron Shells Brown?

There’s nothing worse than baking up tray of macaron shells only to see they’ve browned! This is caused by overbaking or hot spots in your oven.

Potential Fixes: Turn down your oven temp by 5-10 degrees F, bake for slightly less long, bake with a pan above the macaron to protect them from the heat, or bake the macarons with two pans.

Macaron Troubleshooting Issue #7: Why Are My Macarons Uneven?

This can be caused by an uneven baking tray or mat, an oven that bakes unevenly, or from uneven piping.

Potential Fixes: Make sure you’re using a good quality pan and silpat mat, test your oven for hot spots, or take your time when piping and use a template to ensure your macarons are consistent in size and shape.

My Tips for Making the Best French Macarons

  • Wipe your mixing bowl and whisk with lemon juice or vinegar. This removes any traces of grease before making your meringue and help your egg whites whip up better!
  • Separate your own eggs and age them if possible! Do not use egg whites from a carton.
  • Measure your ingredients in grams with a kitchen scale. You really need to be precise with this recipe and your macarons will turn out best if the ingredients are weighed.
  • If you want to color your macarons, use gel food coloring! Liquid food coloring can throw off the consistency of the macaron batter.
  • Use a macaron mat or print out a template to help you pipe consistently sized macarons.
  • FIRMLY bang/drop your pans on your counter after piping your macarons. This helps release any air bubbles that may be trapped and prevent cracked or hollow shells.
  • Rest the macarons for 30 minutes before they’re baked to allow them to develop a skin.
  • Pipe a small number of macarons on a few sheets to test your oven for hot spots and see if it bakes accurately. This way you won’t waste a whole tray of macs if your oven runs hot or cold.
  • Let your macarons mature! Letting them rest overnight while they are filled softens them (in a good way) and allows the flavors to develop.

Making French Macarons in Advance & Storage Tips

  • French macarons need to mature overnight (or ideally 24 hours) in the fridge before being eaten! They taste best 24 hours after being made.
  • Filled Macarons can be stored at room temperature for up to 2 days in an airtight container.
  • Filled Macarons can be refrigerated for up to 5 days in an airtight container.
  • Filled macarons can be frozen for up to a month, but the length can vary based on the filling.
  • Unfilled macaron shells can be frozen for up to a month in an airtight container.
  • Your filling can be made ahead of time too or save any leftover filling! It can be stored in an airtight container in the fridge for up to a week or in the freezer for up to a month.

Some of my Macarons seem undercooked when I look at the bottom. They batter still seems raw. The more I keep putting it in the oven the harder the shell gets. Should I be concerned about this matter or is it okay for me to leave it like that?

Hi Sanuli,

Are you able to peel them off the mat cleanly, or are they sticking? If they're sticking I'd recommend baking them a bit longer, especially if the center seems raw!

How do I make my macarons fat mine are to thin?

Hi Laura,

If your macarons are baking up thin, it might mean that either your slightly over-mixing your batter so it can't keep it's shape once its piped, or you may be banging your pans too much and that might be causing them to overspread. I'd recommend trying to mix your batter a tiny bit less next time and see if that helps. Hopefully it does, fingers crossed your next batch!
