How Many Calories Are In Zucchini And Squash? | Lean Calorie Facts

Calories In Zucchini And Squash By Portion Size

Here’s the straight math cooks use at home. A full cup of raw chopped zucchini lands near 21 kcal. A full cup of raw sliced yellow squash lands near 18 kcal. That’s the baseline for salads, sautés, and snack plates. If you scoop a half cup, just halve those numbers. Easy, fast, and repeatable.

Portion & Prep	Zucchini (kcal)	Yellow Squash (kcal)
1/2 cup, raw	~10–11	~9
1 cup, raw	21	18
1 cup, boiled & drained	27	36

Those values match the lab entries you can check any time on MyFoodData for zucchini and the matching page for summer squash. Shopping or storing? The USDA SNAP-Ed zucchini guide lists simple storage tips that keep texture crisp.

Zucchini Vs. Yellow Squash: Calorie Breakdown

Both sit in the summer squash family, and both are light. Zucchini edges up a touch by the cup because chopped pieces pack the measure a bit tighter. Yellow squash sliced thin shows a slightly smaller number by weight. On the plate, the gap feels tiny. The bigger swing comes from cooking style and extras.

Raw cups look close on macros too. Zucchini brings about 3.9 g carbs and 1.5 g protein per cup. Yellow squash sits near 3.8 g carbs and 1.4 g protein per cup. Sodium stays low. Water content runs high, which boosts meal volume without much energy.

Raw, Boiled, Or Roasted: What Changes The Numbers

Heat changes texture and water. That shifts per-cup math. Boiled or steamed zucchini rises from 21 to 27 kcal per cup as slices get denser after losing water. Cooked yellow squash shows a larger bump to 36 kcal per cup for the same reason.

Roasting reads different again. The veg dries on the edges and picks up browning. If you add oil, the pan brings the real jump. One teaspoon of olive oil adds about 40 kcal to that cup. A teaspoon of butter brings about 34 kcal. None of that makes the dish “off limits”; it just means your serving deserves a quick note if you track.

How Many Calories In Zucchini And Squash Per Cup?

Stick with the core numbers and you’ll be set in any kitchen. A raw cup sits at 18–21 kcal depending on the mix and cut. A cooked cup sits near 27–36 kcal when boiled and drained. If the recipe calls for oil or cheese, add the extras listed in the card above. If breaded and fried, the count climbs fast because crumbs and oil hold on tight.

Smart Ways To Keep The Count Low

Keep the peel on. It adds fiber with no real calorie change and helps slices hold shape. Salt near the end when cooking to avoid sogginess. Drain well after boiling. If roasting, use a light hand with oil: measure, don’t pour. A spray bottle helps coat surfaces without puddles. Herbs, chili flakes, garlic, and lemon juice bring big flavor for a tiny hit of energy.

Hungry for noodles? Zucchini ribbons or spirals carry sauces well. Toss with warm marinara and a shaving of parmesan. The bowl eats like pasta with a fraction of the calories. Roasting yellow squash rounds with smoked paprika and a squeeze of lemon adds pop without moving the numbers much.

Portion Clues You Can See

No scale nearby? A half cup of sliced squash looks like a cupped palm. A full cup looks like a baseball mound on a small plate. A medium zucchini weighs about 190–200 g; half of that sliced makes a generous cup once cooked. Slices shrink a bit in the pan, so plan a little extra volume if you want a full cup after boiling.

Micronutrients Worth Mentioning

Calories aren’t the whole story. A cup of raw zucchini brings vitamin C, potassium, and small amounts of folate. Yellow squash gives similar support. Both are mostly water, so they lend hydration to meals. For exact vitamin lines and daily values, the linked MyFoodData pages list the full panel.

Swaps, Mixes, And Meal Ideas

Try half pasta and half zucchini noodles for a lighter bowl that still feels hearty. Fold grilled squash into tacos with black beans and salsa. Pile ribbons over toast with ricotta and mint. Slide coins into omelets. Add raw matchsticks to slaws for crunch. None of these moves push calories far unless extra fat or cheese arrives in large spoonfuls.

When Winter Squash Shows Up

Butternut, acorn, and friends sit in a different lane. They taste sweeter and pack more energy per cup. Raw butternut runs around 63 kcal per cup, and cooked winter types often land near 70–80 depending on cut and water. That makes them great for stews and roasted sides, just not a one-to-one stand-in for summer squash when your plan leans low-cal.

Cooking Methods And Calorie Math

Stovetop

Sauté quickly over medium-high heat. Keep the pan hot so slices sear and release easily. Use a measured teaspoon of oil, not a free pour. Stir just enough to prevent sticking. Pull when they turn tender-crisp.

Oven

Roast on a sheet at high heat. Spread in a single layer. A quick flip at the halfway point colors both sides. Finish with lemon and herbs, not extra oil.

Microwave

Steam in a covered bowl with a splash of water. Two to three minutes softens coins without added fat. Drain any liquid so the seasoning sticks.

Spice Pantry Shortlist

Garlic powder, smoked paprika, cumin, oregano, crushed red pepper, lemon zest, and black pepper handle nearly any pan of squash. Mix and match, then taste before adding more oil.

Grocery And Storage Tips

Pick firm, glossy squash with intact stems. Smaller ones tend to be less watery. Store unwashed in the fridge; most keep a week. When a few get ahead of you, shred and freeze in flat bags. Squeeze out water after thawing, and the shreds slide into sauces, eggs, and quick breads with a small calorie lift for a big bump in moisture.

Second Table: Add-Ins That Change The Count

These are common extras with simple measures so you can budget at a glance.

Bread crumbs	1 tbsp	~20
Marinara	1/2 cup	~60
