Easy Vegetarian Dinner Recipe: One-Pan Garlic Butter Veggie Skillet That Tastes Like a Cheat Code

Ingredients

• 3 tablespoons unsalted butter (or plant-based butter for vegan)
• 1 tablespoon olive oil (helps prevent burning and adds flavor)
• 5–6 cloves garlic, finely minced
• 1 small red onion, thinly sliced
• 1 red bell pepper, sliced into strips
• 1 yellow bell pepper, sliced
• 2 cups broccoli florets
• 1 medium zucchini, halved and sliced into half-moons
• 1 cup cherry tomatoes, halved
• 1 cup cremini mushrooms, sliced
• 1 can (15 oz) chickpeas, drained and rinsed (optional but encouraged)
• 1 teaspoon Italian seasoning or dried oregano
• 1/2 teaspoon smoked paprika (for depth)
• 1/4–1/2 teaspoon red pepper flakes (optional heat)
• Salt and freshly ground black pepper, to taste
• 1 tablespoon lemon juice (plus extra wedges for serving)
• 2 tablespoons fresh parsley, chopped (or basil, if you’re feeling fancy)
• Grated Parmesan for serving (optional; skip for vegan)

Step-by-Step Instructions

1. Heat the pan: Place a large skillet over medium-high heat. Add olive oil and 2 tablespoons of the butter. When the butter melts and foams, you’re ready for veggies.
2. Sweat the aromatics: Add the onion and a pinch of salt.

   Cook 2–3 minutes until softened. Stir in the garlic and cook 30–45 seconds until fragrant—don’t let it brown.

3. Build the base: Add bell peppers and mushrooms. Cook 3–4 minutes, stirring occasionally, until they start to soften and the mushrooms release their juices.
4. Add the sturdy veg: Toss in broccoli with Italian seasoning, smoked paprika, red pepper flakes, and a good pinch of salt and pepper.

   Cook 3–4 minutes. If the pan gets dry, add a splash of water to steam and tenderize.

5. Quick-cook veggies: Stir in zucchini and chickpeas (if using). Cook another 3 minutes until zucchini is just tender but not mushy.

   We’re going for vibrant and crisp-tender.

6. Finish with butter and acid: Reduce heat to low. Stir in the remaining 1 tablespoon butter and the lemon juice. Toss until glossy and unified.

   Taste and adjust salt, pepper, and heat.

7. Fresh herbs + serve: Turn off heat. Fold in parsley. Top with grated Parmesan if you like.

   Serve hot with crusty bread, over rice, or on quinoa. Chef’s kiss.

How to Store

• Fridge: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Not ideal because zucchini and mushrooms get watery, but it’s fine in a pinch—freeze up to 2 months.
• Reheat: Skillet on medium with a splash of water or stock to rehydrate. Microwave works too—60–90 seconds per serving, stirring halfway.
• Meal prep tip: Keep lemon and herbs separate until serving for brighter flavor.

Why This is Good for You

• Fiber-rich: Broccoli, peppers, and chickpeas help keep you full and support digestion.

  Your future self says thanks.

• Antioxidants for days: Bell peppers and tomatoes bring vitamins A and C, which support skin, immunity, and recovery.
• Healthy fats: Olive oil and a bit of butter make fat-soluble vitamins more absorbable—flavor with benefits.
• Protein boost: Chickpeas add plant protein. Toss in tofu or tempeh if you want an even bigger bump.
• Low effort, high consistency: The best “diet” is one you can stick to. This is weeknight-proof, IMO.

Common Mistakes to Avoid

• Overcrowding the pan: If your skillet is small, cook in batches.

  Too many veggies = steaming, not sautéing.

• Burning the garlic: Add it after the onions soften and keep heat moderate. Bitter garlic ruins good vibes fast.
• Skipping acid: Lemon juice brightens everything. Without it, the dish tastes flat.

  Don’t skip.

• Overcooking zucchini: It goes from perfect to mush in minutes. Add near the end for best texture.
• Underseasoning: Veggies need salt. Taste as you go and at the end.

  Seasoning is not optional—FYI.

Different Ways to Make This

• Make it vegan: Swap butter for plant-based butter or use all olive oil. Skip Parmesan or use a vegan alternative.
• Add protein: Pan-seared tofu cubes, tempeh, or a can of white beans turn this into a full meal.
• Spice profiles: Go Mediterranean with oregano and olives; Tex-Mex with cumin and a squeeze of lime; or Indian-inspired with garam masala and a pat of ghee.
• Carb companions: Serve over couscous, brown rice, quinoa, or garlicky orzo. Or tuck into warm pita with a dollop of yogurt.
• Cheese it up: Crumbled feta, shaved Parmesan, or a dollop of pesto takes it into “how is this so good?” territory.
• Roast-first option: Roast broccoli and peppers at 425°F (220°C) for 12–15 minutes, then finish in the skillet with garlic butter for extra char.

FAQ

Can I use frozen vegetables?

Yes, but thaw and pat them dry first to avoid excess water.

Start with the sturdier veggies in the pan and add delicate ones last so the texture doesn’t turn soggy.

What’s the best pan to use?

A large stainless steel or cast-iron skillet (10–12 inches) works best. You want plenty of surface area for browning without steaming.

How do I make it spicier?

Add more red pepper flakes or a drizzle of chili crisp at the end. A pinch of cayenne in the spice mix also works great.

Can I prep this ahead?

Absolutely.

Slice the veggies and store them in separate containers. Mince garlic and chop herbs the day of for maximum freshness.

What can I substitute for chickpeas?

White beans, lentils, cubed tofu, or tempeh are all excellent. If using tofu, press it first and sear separately for best texture.

Is there a dairy-free way to get the same flavor?

Use a quality plant-based butter and finish with a splash of olive oil.

Nutritional yeast sprinkled on top adds a buttery, cheesy vibe without dairy.

How do I keep the veggies crisp-tender?

Cook in stages: sturdy veg first, delicate veg last. Don’t walk away from the pan—stir occasionally and keep the heat medium-high.
