15-minute Sauteed Zucchini and Squash With Garlic and Butter

Weeknight side alert: zucchini and squash in garlic-butter, seared hot for golden edges, bright lemon, and herbs—fast, simple, insanely good.

You want a side that tastes like a chef cooked it, but your clock says, “nope.” This delivers: bold garlic, buttery gloss, and caramelized edges in less time than a rice cooker’s warm-up. It’s the simplest upgrade for any chicken, fish, steak, or pasta dinner—aka your new weeknight hack. And yes, it’s veggie-forward without tasting like homework. Ready to make the stove do the flexing?

What Makes This Special

Most vegetable sides collapse into mush or drown in sauce. Not this one. The magic is high heat, quick sear, and a buttery garlic finish that clings to every bite. You get the best of both worlds—crisp-tender texture and deep, savory flavor—with just a handful of ingredients.

It’s also highly adaptable. Want a little heat? Add red pepper flakes. Want brightness? Lemon juice at the end. Want restaurant-level vibes? Finish with herbs and Parmesan. In 15 minutes, you go from “I guess we’ll steam something” to “Wow, who made this?” FYI: it’s you.

What Goes Into This Recipe – Ingredients

• 2 small-to-medium zucchini (about 1 lb total), sliced into 1/4-inch half-moons
• 2 small yellow squash (about 1 lb total), sliced into 1/4-inch half-moons
• 2 tablespoons unsalted butter, divided
• 1 tablespoon extra-virgin olive oil
• 3 garlic cloves, minced (about 1 tablespoon)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon freshly ground black pepper
• Pinch of red pepper flakes (optional, for heat)
• 1 teaspoon lemon zest + 1 tablespoon fresh lemon juice
• 2 tablespoons chopped fresh parsley or basil (for garnish)
• 2 tablespoons freshly grated Parmesan (optional)
• Optional add-in: 1 small shallot, thinly sliced

Equipment: Large skillet (12-inch works best), cutting board, sharp knife, spatula or tongs.

How to Make It – Instructions

1. Prep the veg. Wash and dry the zucchini and squash thoroughly. Slice into 1/4-inch half-moons. Pat dry again with paper towels—surface moisture = steam, not sear.
2. Preheat the skillet. Set a large skillet over medium-high heat for 2–3 minutes. You want it hot enough that a drop of water sizzles and vanishes.
3. Add fats. Melt 1 tablespoon butter with the olive oil. The oil raises the smoke point so the butter won’t burn. Swirl to coat the pan.
4. First sear. Add half the zucchini and squash in a single layer. Don’t crowd. Cook undisturbed for 3–4 minutes until you see golden spots. Flip or toss and cook another 2–3 minutes until crisp-tender. Transfer to a plate. Repeat with the remaining veg, adding a splash of oil if the pan looks dry.
5. Garlic time. Return all the vegetables to the pan. Make a clear spot in the center, add the remaining 1 tablespoon butter and the minced garlic. Cook the garlic in the butter for 30 seconds until fragrant (no longer), then toss everything together.
6. Season and brighten. Sprinkle in salt, pepper, and red pepper flakes (if using). Add lemon zest and lemon juice. Toss quickly so the butter emulsifies with the lemon—tiny flavor bomb moments.
7. Finish strong. Taste and adjust seasoning. Remove from heat. Shower with herbs and, if you like, Parmesan. Serve immediately while edges are still snappy.
8. Optional shallot move. If using shallot, sauté it for 1–2 minutes after step 3, before adding the vegetables. This adds a sweet, savory backbone.

Pro tip: If you’re cooking for a crowd, work in batches. Overcrowding the pan turns your sear into a steam session—aka the enemy of flavor.

Preservation Guide

• Cool quickly: Spread leftovers on a plate to cool for 10–15 minutes, then transfer to a shallow container.
• Refrigerate: Store in an airtight container for up to 3–4 days.
• Reheat: Best in a hot skillet with a touch of oil or butter for 2–3 minutes to revive the edges. Microwave works in a pinch, but expect softer texture.
• Freezing: Not ideal. The texture softens considerably once thawed. If you must, freeze flat in a zip-top bag for up to 2 months and plan to use in soups, frittatas, or sauces—not as a standalone side.
• Make-ahead: You can slice the vegetables up to 24 hours ahead. Store them wrapped in a paper towel inside an airtight container to wick away moisture.

What’s Great About This

• Speed: From pan heat to plated goodness in about 15 minutes.
• Flavor density: Garlic-butter gloss + lemon pop + herb freshness.
• Texture: Crisp-tender, golden edges—no soggy sadness.
• Flexible: Switch herbs, add spice, toss in cheese, or keep it clean.
• Diet-friendly: Naturally gluten-free and low-carb; easy to make dairy-free.
• Budget-smart: Peak produce, minimal pantry staples, maximum payoff.
• Plays well with others: Works with grilled meats, salmon, pasta, grain bowls—basically everything.

Common Mistakes to Avoid

• Overcrowding the pan: Too many slices = trapped steam. Cook in batches for color and snap.
• Low heat: Medium-high heat is your friend. Low heat turns veggies watery and limp. No thanks.
• Adding garlic too early: Garlic burns fast. Bloom it at the end in butter, then toss.
• Skipping the dry step: Wet vegetables steam. Pat dry for better sear and flavor.
• Overcooking: You want crisp-tender. If slices bend like noodles, you went too far.
• Salting too soon: Salt draws out moisture. Season after searing for best browning.
• Wrong pan: A large skillet (stainless or cast iron) beats a small nonstick when you want color.
• Forgetting acidity: A squeeze of lemon wakes up butter and garlic. Don’t skip it.

Variations You Can Try

• Italian trattoria: Add sliced shallot, thyme, and finish with Parmesan and a drizzle of good olive oil.
• Greek-ish: Oregano, lemon, and crumbled feta with a few olives tossed in at the end.
• Spicy kick: Red pepper flakes + a pinch of smoked paprika; finish with parsley and lemon.
• Pesto finish: Stir in 1–2 tablespoons basil pesto off heat for a glossy, herby coating.
• Sesame-soy: Swap lemon for 2 teaspoons soy sauce and 1 teaspoon rice vinegar; finish with toasted sesame oil and seeds.
• Bacon upgrade: Cook 2 slices chopped bacon first; use the drippings with a knob of butter to sauté the veg. Yes, it slaps.
• Vegan/dairy-free: Use only olive oil or a vegan butter; add a squeeze of lemon and nutritional yeast for cheesy vibes.
• Tomato pop: Add a handful of halved cherry tomatoes in the last 2 minutes for juicy bursts.

FAQ

Do I have to use both zucchini and yellow squash?

Nope. You can use all zucchini or all yellow squash. The method stays the same—just keep the slices even and the pan hot for good browning.

Should I peel the zucchini or squash?

No peeling needed. The skin is thin, edible, and adds color and texture. Plus, it helps the slices hold their shape during a quick sear.

How do I keep the vegetables from getting soggy?

Three keys: hot pan, dry slices, and no overcrowding. Sear undisturbed to build color, then flip. Season after browning to avoid drawing out water too early.

What kind of pan works best?

A wide stainless-steel or cast-iron skillet is ideal for strong searing. Nonstick works in a pinch, but it won’t brown as aggressively. Bigger surface area = better results, IMO.

Can I make this without butter?

Yes. Use all olive oil for dairy-free or vegan. For richness, finish with a splash of good extra-virgin olive oil and a squeeze of lemon. Nutritional yeast adds a savory note if you miss the Parmesan.

How can I scale this up for a crowd?

Cook in batches and keep finished vegetables on a sheet pan in a 200°F oven. Alternatively, use two skillets at once. Don’t cram everything into one pan—steam is the villain here, FYI.

Can I add protein to make it a full meal?

Absolutely. Toss in cooked shrimp, rotisserie chicken, crumbled Italian sausage, or chickpeas during the last minute to warm through. Adjust salt and lemon to taste.

Is this recipe keto or gluten-free?

Yes to both. It’s naturally low in carbs and contains no gluten. Just check your add-ins (like soy sauce or store-bought pesto) if you’re being strict.

What should I serve this with?

Grilled salmon, roasted chicken, steak, or pork chops. It’s also great over couscous, polenta, or tossed with pasta. Add a fried egg on top and call it brunch—no one will complain.

Can I meal-prep this?

Yes, with expectations. It reheats well but softens slightly. Store for up to 3–4 days, then reheat in a hot skillet to bring back some edge. Use leftovers in omelets, grain bowls, or quesadillas, TBH.
