Stale croissants are a common problem. They lose their flaky charm and often end up in the trash. This recipe transforms them into something better: crisp, buttery croutons that add a touch of luxury to any salad or soup.

The key is controlled low-temperature baking. This dries the croissant pieces thoroughly without burning the butter, resulting in a shatteringly crisp texture that holds up in dressings and broths.
You only need a few pantry staples and 20 minutes. The result is a versatile topping that elevates simple meals into something special.
Why You'll Love This Recipe
About the Ingredients
4 large day-old croissants (about 300g total)
Slightly stale works best. If using fresh, let them sit uncovered for a few hours.
1/4 cup (60g) unsalted butter, melted
Use salted butter and reduce added salt, or substitute olive oil for a dairy-free version.
2 tablespoons olive oil
Extra virgin adds flavor; a neutral oil works too.
2 cloves garlic, minced
Fresh garlic is best; use 1/2 teaspoon garlic powder if in a pinch.
1 teaspoon dried thyme
Or use 1 tablespoon fresh thyme leaves.
1/2 teaspoon salt
Adjust to taste; if using salted butter, reduce to 1/4 teaspoon.
1/4 teaspoon black pepper
Freshly ground recommended.
Tips & Tricks
- Cut croissants into uniform 1-inch pieces for even baking.
- Toss well to coat every piece with butter mixture.
- Spread in a single layer on the baking sheet; overcrowding causes steaming.
- Stir halfway through baking for even crispness.
Pro Tips
Step-by-Step Instructions
1. Preheat oven
Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
2. Cut croissants
Slice croissants into 1-inch cubes. Aim for uniform size for even toasting.
3. Mix butter mixture
In a large bowl, combine melted butter, olive oil, garlic, thyme, salt, and pepper. Whisk well.
4. Toss croissant cubes
Add croissant cubes to the bowl and gently toss until every piece is coated. Use a spatula to avoid crushing.
5. Arrange on sheet
Spread cubes in a single layer on the prepared baking sheet. Do not overcrowd.
6. Bake
Bake for 15 minutes, then stir. Continue baking for 5-10 minutes until golden brown and crisp. The croutons should feel dry and hard when pressed.

Frequently Asked Questions
Q: Can I use fresh croissants?
Yes, but fresh croissants are softer and may need a few extra minutes in the oven. Cut them smaller and check frequently to avoid burning.
Q: How do I keep croutons crispy in soup?
Add them right before serving. If storing, keep them separate and sprinkle on top just before eating.
Q: Can I make these vegan?
Absolutely, substitute the butter with vegan butter or additional olive oil. Use a 1:1 ratio.
