How to Substitute Spinach for Kale
A Simple Swap Guide
When considering meal preparation and recipe adaptation, cooks often find themselves seeking appropriate substitutes for certain ingredients, either due to personal preference, dietary restrictions, or availability. Substituting spinach for kale is a common consideration in the kitchen due to their nutritional similarities and the versatility of both leafy greens. Each brings its own set of characteristics to dishes, yet they can play similar roles in a variety of culinary contexts.
Spinach, with its tender leaves and milder flavor, offers a less pronounced taste and a softer texture compared to the slightly bitter and sturdy nature of kale leaves. This makes spinach an excellent alternative in raw applications, such as salads, where its subtlety complements other ingredients without overwhelming them. Moreover, spinach requires less cooking time than kale, which can be advantageous in quick meals.
In cooked dishes, especially those where kale is called to be simmered or baked, spinach can be incorporated with a few adjustments. Since spinach wilts and reduces in volume significantly, it is often necessary to use a larger quantity of spinach to achieve a similar bulk as one would with kale. Also noteworthy is spinach's nutrient content, as it is rich in vitamins A and C as well as iron and fiber, making it not just a convenient but also a healthful replacement for kale in many recipes.

Preparation Techniques
When substituting spinach for kale, chefs should pay close attention to the preparation steps to ensure that the dish’s texture and flavor are well balanced. Proper washing, drying, cutting, and cooking techniques are crucial for achieving the best results in recipes.
Washing and Drying
Spinach leaves often harbor dirt and grit, so thorough washing is crucial. To wash spinach, one should:
Fill a large bowl with cold water.
Submerge the spinach leaves in the water, gently swishing them around to dislodge any dirt.
Lift the leaves out and into a colander, allowing the dirt to settle at the bottom of the bowl.
Repeat until the water stays clear.
To dry spinach, one can:
Use a salad spinner to remove excess water quickly.
Alternatively, lay the leaves out on a clean kitchen towel or paper towels and gently pat them dry.
Slicing and Chopping
Properly slicing and chopping spinach to match kale’s texture can affect how it integrates into a recipe. Chefs should consider the following:
For raw dishes, like salads, chop the spinach more coarsely to give the dish the hearty texture typically provided by kale.
In cooked preparations, finely chop the spinach since it wilts to a smaller volume compared to kale and cooks more quickly.
Cooking Methods
Chefs can choose various cooking methods for spinach when used in place of kale. These include:
Sautéing: Quickly sauté spinach over medium heat with a little oil until just wilted; typically takes 1 to 2 minutes.
Steaming: Steam spinach for a brief period to retain its vibrant color and nutrients; usually takes about 2 minutes.
Blanching: If a recipe calls for cooked kale, blanching spinach for 30 seconds in boiling water can slightly toughen its delicate leaves, mimicking kale's firmer texture.
By applying these specific preparation techniques, spinach can seamlessly take the place of kale in a variety of dishes.
Substitution Basics
When substituting spinach for kale, one must consider the differences in flavor, cooking time, and texture. Precise adjustments ensure the integrity of the dish is maintained.
Determining Ratios
To replace kale with spinach, the ratio is typically 1:1, meaning if the recipe calls for one cup of kale, use one cup of spinach. However, due to spinach's more delicate nature and higher water content, slight variations may be needed. For example, in raw applications like salads, one might prefer a bit less spinach, as it wilts more quickly.
Adjusting Cooking Times
Spinach cooks more quickly than kale due to its tender leaves. When cooking dishes that originally use kale, reduce the cooking time for spinach. For instance, if a soup recipe includes kale for 15 minutes, spinach should be added in the last 3-5 minutes. Sautéing spinach instead of kale requires just a minute or two, as opposed to kale which might need 5-10 minutes.
Flavor Balancing
Kale has a robust, slightly bitter taste, and spinach offers a milder flavor. To compensate, adjustments in seasoning might be necessary. Use a pinch of salt or a dash of acid like lemon juice or vinegar to enhance the spinach’s flavor. When substituting in recipes where kale's heartiness is a counterpoint to other strong flavors, one might need to increase other herbs or spices to maintain the dish's balance.
Recipes and Pairings
In substituting spinach for kale, it's essential to consider the texture and flavor profile of the dish. The mildness of spinach makes it versatile in a variety of recipes, from thirst-quenching smoothies to hearty casseroles.
Smoothies and Juices
For smoothies and juices, spinach is an excellent kale substitute due to its softer leaves, which blend smoothly. Recipes like a green detox smoothie can seamlessly incorporate spinach without compromising the vibrant green color and nutrient density. In fact, a typical smoothie recipe might call for a cup of spinach as a direct replacement for a cup of kale.
Soups and Stews
In soups and stews, spinach's gentle flavor and quicker wilting time make it a favorable ingredient for last-minute additions. A soup like lentil spinach soup can benefit from spinach added in the final minutes of cooking, preserving its color and nutrient content. For dishes like minestrone or a hearty bean stew, substitute an equal amount of spinach for kale.
Salads and Dressings
When preparing salads and dressings, spinach's tender quality requires less preparation than kale. It is well-suited for a raw application where its delicacy can be appreciated. For instance, a spinach salad with a tangy vinaigrette can replace a kale salad, where the spinach should be lightly tossed rather than massaged.

Casseroles and Baked Dishes
In casseroles and baked dishes such as lasagna or a quiche, spinach can replace kale without major recipe alterations. Casseroles often require cooking greens first, and spinach should be wilted briefly due to its tender nature. For layered dishes like lasagna, spinach can be used fresh or just lightly sautéed before layering. A pasta dish can equally benefit from the substitution, providing a mild, earthy foundation without overpowering other flavors.
