One-Pot Lemon Broccoli Pasta

Featured in: One-Pot Recipes

This one-pot lemon broccoli pasta combines tender spaghetti, fresh broccoli florets, and a silky lemon-garlic sauce for a vibrant spring meal. The entire dish cooks together in one pan, creating a naturally creamy sauce as the pasta releases its starch into the broccoli-infused vegetable broth and milk base. Simply sauté garlic, add pasta and broccoli with liquid, simmer until al dente, then finish with bright lemon zest and juice, Parmesan cheese, and optional red pepper flakes. Perfect for weeknight dinners, easily customizable with substitutions like chickpeas for protein or different vegetables for seasonal variations.

My roommate wandered into the kitchen one Wednesday night, sniffed the air, and asked if I was cooking summer in a pot. I laughed because it was still cold outside, but the lemon and garlic had filled the apartment with this impossibly bright smell. I had tossed everything into one pan because I was too tired to deal with multiple dishes, and somehow it turned into the kind of meal that makes you forget you were exhausted five minutes ago. That accidental discovery became my go-to whenever I need something quick, comforting, and just a little bit sunny.

I made this for my sister when she came to visit during finals week, and she ate two bowls standing at the counter before she even sat down. She kept saying it tasted like spring break, which didnt make sense until I realized she meant it felt like a vacation from her usual stress-eating routine. We ended up talking for an hour over the pot, twirling pasta and stealing bites of broccoli, and she left with the recipe scribbled on the back of a grocery receipt. Now she texts me photos every time she makes it, usually with some variation I never thought of, like adding peas or using lime instead of lemon.

Ingredients

  • 12 oz dried spaghetti or linguine: The long noodles soak up the broth beautifully as they cook, and I like how they tangle with the broccoli in a way that feels generous.
  • 4 cups broccoli florets, bite-sized: Cut them small enough that they soften at the same pace as the pasta, and dont worry if a few pieces get a little jammy at the edges.
  • 4 cloves garlic, thinly sliced: Slicing lets the garlic melt into the sauce without burning, and it gives you these sweet, tender little ribbons throughout.
  • 1 small onion, finely chopped (optional): I skip it when Im lazy, but it adds a quiet sweetness that rounds out the sharper lemon and garlic.
  • 4 cups vegetable broth or water: Broth makes it richer, but Ive used water plenty of times and it still works because the pasta releases its own starch.
  • 1/2 cup whole milk or plant-based milk: This is what turns the broth into a silky sauce instead of just pasta water, so dont skip it.
  • Zest and juice of 1 large lemon: The zest is where the magic lives, bright and almost floral, while the juice adds the tang that wakes everything up.
  • 1/4 cup freshly grated Parmesan cheese: Grate it yourself if you can, the pre-shredded stuff doesnt melt the same way and you lose that creamy finish.
  • 2 tbsp olive oil: Just enough to get the garlic going and add a little richness without making it heavy.
  • 1/2 tsp sea salt, or to taste: Start with less because the broth and Parmesan add their own saltiness, then adjust at the end.
  • 1/4 tsp black pepper: Freshly cracked is best, it adds a gentle warmth that doesnt compete with the lemon.
  • 1/4 tsp crushed red pepper flakes (optional): I like a tiny kick, but my sister doubles it, so this is really about your mood.
  • Fresh basil or parsley, chopped (optional): A handful on top makes it look like you tried harder than you did, and the green against the lemon is just pretty.

Warm the garlic:
Heat the olive oil over medium heat and add the garlic, letting it sizzle gently until it smells like the best part of an Italian restaurant. If youre using onion, toss it in too and let it soften for a minute or two, just until it turns translucent and sweet.
Add everything to the pot:
Drop in the dried pasta, broccoli florets, vegetable broth, and milk all at once, then give it a good stir so nothing sticks to the bottom. Bring it to a boil, then lower the heat to a steady simmer.
Simmer and stir:
Cook uncovered for 10 to 12 minutes, stirring every couple of minutes so the pasta doesnt clump and the broccoli gets tender without turning to mush. The liquid will reduce into a creamy, starchy sauce that clings to everything.
Finish with lemon and cheese:
Stir in the lemon zest, lemon juice, Parmesan, salt, black pepper, and red pepper flakes if youre using them. Taste it and adjust the seasoning, adding more lemon or salt if it needs a boost.
Let it rest:
Take the pot off the heat and let it sit for 2 to 3 minutes so the sauce thickens up just a little more. Serve it hot, with extra Parmesan and a sprinkle of fresh herbs if you have them.

The first time I brought this to a potluck, someone asked if I had catered it, and I just laughed because I had made it in my pajamas an hour before. It became the thing people requested, and I started to realize that the best dishes arent always the complicated ones. Sometimes its just about throwing good ingredients into a pot and letting them do their thing while you sit down and catch your breath.

How to Make It Your Own

This recipe is basically a template for whatever vegetables or proteins you have on hand. Swap the broccoli for asparagus tips or thin-sliced zucchini in the spring, or toss in a handful of frozen peas during the last two minutes of cooking. If you want more protein, stir in a can of drained chickpeas or white beans at the end, or top each bowl with a soft-boiled egg. I have also added cooked shrimp and it turned into something that felt way fancier than the effort required.

Storing and Reheating

Leftovers keep in the fridge for up to three days in an airtight container, though the pasta will soak up more sauce as it sits. When you reheat it, add a splash of milk or broth and warm it gently on the stove, stirring until it loosens up and looks creamy again. I actually love it the next day because the flavors have had time to settle, and sometimes I eat it cold straight from the container for lunch, which is not elegant but absolutely works.

Pairing and Serving Ideas

This pairs beautifully with a crisp white wine like Pinot Grigio or Sauvignon Blanc, something with enough acidity to match the lemon without fighting it. If youre feeding a crowd, serve it with a simple arugula salad dressed in olive oil and a squeeze of lemon, or some crusty bread for mopping up the extra sauce. It also works as a side dish next to grilled chicken or fish, though I usually just make a double batch and call it dinner.

  • Top with toasted pine nuts or slivered almonds for a little crunch and richness.
  • Drizzle with a bit of good olive oil right before serving to make it feel a little more special.
  • Try adding a handful of baby spinach in the last minute of cooking for extra greens without any extra effort.

Recipe FAQ

Can I use fresh pasta instead of dried?

Fresh pasta will cook much faster than dried. Add it in the final 3-4 minutes of cooking to prevent overcooking and mushiness. Reduce the initial simmering time accordingly and monitor closely for desired tenderness.

How do I prevent the pasta from sticking?

Stir frequently throughout cooking, especially in the first few minutes after adding the pasta. Use a wooden spoon to gently break up any clumps. The frequent stirring helps distribute heat evenly and prevents the pasta from sticking to the bottom of the pot.

What if the sauce is too thin?

Continue simmering uncovered for another 2-3 minutes to allow more liquid to evaporate. The sauce thickens as it cools slightly. If still too thin, mix a tablespoon of cornstarch with water and stir it in while simmering for 1 minute.

Can I make this vegan?

Yes. Substitute plant-based milk for whole milk and use vegan Parmesan or nutritional yeast for the cheese. The dish maintains its creamy texture and bright flavor profile while remaining completely plant-based.

How should I store leftovers?

Transfer cooled pasta to an airtight container and refrigerate for up to 3 days. Reheat gently in a pot with a splash of vegetable broth to restore the sauce consistency. You may need to add extra lemon juice to refresh the bright flavors.

What vegetables work well as substitutes?

Asparagus, zucchini, snap peas, and spinach all work beautifully. Cut vegetables to similar sizes for even cooking. Leafy greens like spinach wilt quickly, so add them in the final 2 minutes. Harder vegetables may need slightly longer cooking time.
