Pisto Manchego is a humble, peasant dish that is often referred to as Spanish ratatouille, or simply 'pisto'. It includes fresh produce such as tomatoes, peppers, zucchini, onion and garlic and sometimes eggplant, depending on the region.
This recipe began as a traditional pisto recipe, with some modifications to create a phenomenal low-FODMAP vegetable stew. I’ve added a few spices that make this vegetarian recipe a savory, slightly sweet delight that will warm your heart. And make you lick the bowl.
Pisto is so versatile, you can eat it with just about anything. Often, you’ll find pisto manchego with eggs (pisto con huevo) as a very popular Spanish meal, but it can be served with meat, fish or poultry, as well. It's perfect paired with Cheddar Almond Flour Drop Biscuits and grated Manchego cheese.
If you love Mediterranean flavors, be sure to try these Spicy Marinated Olives, a Mediterranean Stir Fry or some Skordalia - which is one of my favorite things.
What is pisto manchego?
Love at first bite. Pisto is referred to as Spanish ratatouille, because it features fresh Mediterranean vegetables and is similar to French ratatouille. It’s a savory summer vegetable stew that is also quite similar to Israeli shakshuka, Italian caponata and Turkish imam bayildi.
‘Pisto’ essentially means ‘crushing or extracting the juice from something’. Manchego means ‘from La Mancha’, referring to the region where it originated. In Spain, each region has its own version. For example, the Andalusian variation is typically made with eggplant.
Zucchini, bell peppers, onion (or leek for low-FODMAP) and garlic (omit for low-FODMAP) are simmered in a tomato olive oil sauce (I use FODMAP-friendly garlic infused olive oil), creating a rich, savory, belly warming traditional harvest recipe.
Some folks confuse this dish with Gazpacho Manchego, which is also a traditional Spanish dish. Gazpacho Manchego is chicken and rabbit stew with a rich tomato broth (and one of the best things I’ve ever eaten, to be honest). This shouldn’t be confused with ‘gazpacho’, which is an Andalusian cold summer soup.
What is ratatouille?
Ratatouille is very similar to Spanish pisto. It originates from the Provence region of France and is also a vegetarian stew made with sliced eggplant, tomatoes, bell peppers, onions, garlic, olive oil and herbs. Pisto is a veggie stew, quite like ratatouille without eggplant (in some regions). It calls for a bit more tomato and the vegetables are chopped, rather than sliced, like in traditional French ratatouille.

Is pisto a low-FODMAP recipe?
Yes! I’ve created a FODMAP-friendly no onion, no garlic recipe, seasoned with low-FODMAP spices. The onion has been replaced with leek (green part only) and the garlic is replaced with garlic-infused olive oil.
I enjoy this as a low-FODMAP breakfast with a fried egg or as a low-FODMAP dinner recipe, served with grilled fish, chicken or shrimp, on top of creamy Skordalia, made with garlic infused olive oil.
Is pisto a keto stew?
Yes! This is an easy keto meal, with simple keto-friendly fruit and vegetables. One serving is only 6g net carbs.

Ingredients
This easy vegetable stew is made with simple ingredients:
- Tomatoes – fresh tomatoes add such a bright flavor.
- Bell peppers – traditionally, pisto is made with green and red bell pepper, but my sweetie isn’t a fan of green bell peppers, so I used two red peppers instead
- Zucchini – these absorb flavors very well and add a nice, soft, almost creamy texture when cooked down
- Onion or leek – if you follow a low-FODMAP diet, use the green part of 1-2 leeks, depending on the size. Otherwise, use one medium yellow onion.
- Garlic – omit for low-FODMAP and use garlic infused olive oil instead of olive oil
- Olive oil or garlic infused olive oil – adds a wonderful flavor and good source of omega-3 fatty acids
- Sherry vinegar – if you don’t have sherry vinegar, use champagne vinegar or apple cider vinegar. The extra acidity balances the sweetness of the other ingredients.
- Sea salt – really enhances the flavors. I also love to use kala namak black salt.
- Optional garnish: I love to top this stew with a garnish of fresh parsley. Parsley is nutrient dense and adds a touch of class to any dish.
What are the best tomatoes for pisto?
Fresh blanched tomatoes are best and yield the best flavor. I like to use tomatoes on the vine or roma, but any fresh tomatoes will work well. If you’re in a pinch, you can use canned tomatoes, but the flavor may not be as robust.
Instructions
This is a very simple, one-pot recipe that can be made in a few easy steps:
Blanch and peel the tomatoes (this is SO easy!). Blanching tomatoes allows the skins to soften and crack, making them easy to peel.
- Bring a large pot of water to a boil and add the tomatoes
- Boil for 2-3 minutes, until the skins begin to crack
Let cool enough to handle.
Remove the skins and chop the tomatoes into half-inch pieces.
Chop the leek or onion, if using.
Chop the zucchini and peppers, and finely chop the garlic, if using.
Sauté the onion (or leek) and garlic (if using) in olive oil or garlic infused olive oil for 1-2 minutes, until fragrant.
- Add the remaining ingredients and simmer until soft
- Serve and savor
How to store
I think the flavors of this dish tend to grow as it sits and makes amazing leftovers. I often keep this in the fridge for easy breakfast meal prep.
Store in a sealed container in the refrigerator for up to 5 days.
It can also be frozen in a tightly sealed container for up to 6 months.
Variations
This is such a versatile recipe and it is highly customizable. Other vegetables can easily be added:
- Any kind of summer squash can be used – yellow, patty pan, crookneck, etc. If you're looking for zucchini recipes or any summer squash recipes, you can use them all here.
- Add chard or other leafy greens – kale or collards are great additions
- Root vegetables or baby corn – are great low-carb keto vegetables to add
- Mushrooms – FODMAP-friendly oyster mushrooms are a great addition. They should be finely chopped and add a nice umami flavor.
- Add some low-FODMAP beans – such as canned adzuki, mung, garbanzo or lentils. Black soy beans are a tasty keto-friendly bean, but are not FODMAP-friendly.
- Include diced winter squash – like pumpkin and butternut
- Other optional seasonings – these are not traditional pisto ingredients, but make for a divine, rich savory stew. I love to add: bay leaf, smoked paprika (pimenton), black pepper, saffron and a little sweetener (I like to use stevia). See the recipe card notes for measurements. Asafoetida is also a great low-FODMAP seasoning to add, as it imparts a garlic and onion flavor to the dish. Simmer just a couple pinches in the olive oil before adding the vegetables and simmer until fragrant (about 30 seconds). Read more about this spice in my Asafoetida Ingredient Spotlight.
Serving suggestions
Serve this as a main dish, as a side with grilled meats and a Cheddar Almond Flour Biscuit or as the best, easy tapas (traditionally, small Spanish savory dishes). It can be served hot or cold.
- Make traditional Spanish pisto manchego with eggs – either fry or poach an egg and serve on top of your pisto. Or, create a Spanish-inspired shakshuka and place the pisto in an oven-safe pan, make small wells in the stew and crack an egg into each well. Bake until set.
- Add sausage – such as chorizo or add jamon, Spanish dry-cured ham.
- Add a protein – and serve with seafood, meat or poultry of choice, Spanish sardines, shrimp, grilled chicken or fish. This is delicious served with leftover Thanksgiving turkey.
- Balsamic vinegar – add a drizzle on top
- Serve as a topping – on keto-friendly Cauliflower Rice or creamy, delicious Skordalia
- Add cheese – grated manchego cheese is amazing!
FAQ

I have so many tomatoes and zucchini from my garden and I found this recipe to use them. Wow it's so easy to make and the flavor is amazing. I did put an egg in it and loved it. Great leftovers - I think it's even better the next day. I'm gonna try it in my instant pot next. Thanks!
