Whether you’ve got fresh spinach from the store or garden, freezing it the right way helps lock in nutrients and flavor for months.
Let’s break down the three best methods to freeze spinach, when to use each one, and how to store it properly.

Why Freeze Spinach?
Freezing spinach isn’t just about saving what you can’t finish—it’s about meal prepping smarter and keeping nutrient-packed greens available year-round. It’s ideal for:
- Making smoothies
- Adding to soups, stews, or omelets
- Boosting pasta sauces or rice dishes
- Blending into pesto or dips
Once frozen, spinach won’t be suitable for salads, but it’s perfect for any recipe where it gets cooked or blended.

Method 3: Freezing Cooked Spinach
Best for: Leftovers, spinach dips, side dishes
If you’ve already sautéed or cooked spinach, you can still freeze it.
Steps:
- Let it cool completely
- Portion into airtight containers or bags
- Label and freeze
- Use within 3 months for best flavor and texture
- Use within 3 months for best flavor and texture
This method is especially great for meal prepping recipes like spinach-stuffed shells or creamed spinach.

How to Use Frozen Spinach
You don’t need to thaw it in most recipes—just toss it in frozen. Here are a few ideas:
- Smoothies: Drop frozen spinach cubes into your blender
- Soups & stews: Stir in the last few minutes of cooking
- Egg dishes: Mix into omelets, quiches, or breakfast muffins
- Pasta sauces: Add to marinara or cream sauces for extra greens

If you do need to thaw spinach (like for dips), place it in the fridge overnight or defrost gently in the microwave, then squeeze out excess liquid.
