Ingredients List

• 2 medium onions (yellow or white), finely diced

How to Make Mirepoix: Step-by-Step

1. Prep Your Veggies: Start by rinsing and peeling your vegetables. Aim for uniform, small dice — roughly 1/4-inch pieces. Don’t stress if it’s a little chunky; rustic mirepoix works just fine!
2. Heat Your Pan: Place a heavy-bottomed skillet or saucepan over medium-low heat. Add your olive oil or butter—this helps soften the veggies gently instead of browning them.
3. Add the Vegetables: Toss in the onions first. After about 2–3 minutes, add carrots and celery along with a pinch of salt. The salt helps draw out moisture, sweating the vegetables without caramelizing.
4. Cook Low and Slow: Stir occasionally, letting the mixture soften but not brown. This should take about 10-15 minutes. Your kitchen will smell amazing right about now!
5. Optional Garlic: If adding garlic, toss it in during the last 1-2 minutes of cooking so it doesn’t burn and turn bitter.
6. Ready to Use: Once the vegetables are translucent and tender but not browned, your mirepoix is ready to serve as the aromatic base.

Mirepoix traces back to 18th-century France and was named after the Duke of Mirepoix, whose chef is credited with popularizing this trio of vegetables. It’s a cornerstone of French cuisine, emphasizing the power of simple, fresh ingredients combined with slow cooking to release flavors naturally. Over centuries, it traveled worldwide, becoming a fundamental flavor base in kitchens everywhere.

Variations & Substitutions: Making It Your Own

Though the classic ratio is 2:1:1 of onion, carrot, and celery, feel free to tweak it:

• Herbes Variées: Add fresh thyme, bay leaf, or parsley for an aromatic lift.
• Leeks or Shallots: For a milder onion flavor, swap onions with finely chopped leeks or shallots.
• Low-Carb Alternative: Substitute carrots with diced fennel or parsnips.
• Garlic Boost: Including minced garlic adds a punch of savory spice.

Storage & Make-Ahead Tips

If you want to save time on busy cooking days, mirepoix is super freezer-friendly:

• Refrigerate: Store in an airtight container for up to 3 days—perfect for quick flavor bases.
• Freeze: Freeze in portion-sized bags or containers for up to 3 months. Use directly from frozen to start sauces and soups.
• Reheat: Gently warm in a pan over low heat, adding a splash of water or broth if needed to soften again.
