Red wine spaghetti skips the stock pot and cooks the pasta straight in a bottle of cabernet. One pot for boiling, one skillet for the garlic and butter sauce. That's the whole promise.
You'll use a full bottle of dry, full-bodied red, so pick something you'd actually drink. A cheap jammy cabernet works fine here. Save a quarter cup before you start, because that splash goes into the sauce at the end and keeps the wine flavor bright instead of cooked out.
The pasta absorbs a lot of liquid as it boils, so don't walk away. Stir it every minute or so. Spaghetti that sits still in wine sticks together in a clump, and no amount of sauce fixes that.
Tips & Tricks
- Reserve the quarter cup of wine before you pour anything into the pot. Once the bottle is in, it's gone.
- Keep a mug next to the stove for the starchy cooking liquid. You need a quarter cup and it's the glue that makes the sauce cling.
- Grate the parmesan before the pasta goes in. The last few minutes move fast.
- Taste a strand at 7 minutes. If it still has a chalky center, give it another minute and check again.
Step-by-Step Instructions
1. Set aside the wine
Measure 1/4 cup of the wine and put it aside in a small glass. You'll add it at the end, off the heat, so the wine flavor stays fresh.
2. Boil water and wine
Pour the remaining wine and the 4 cups of water into a large pot. Set it over high heat and bring it to a boil. It'll smell strongly of wine as it heats, which is normal.
3. Cook the spaghetti
Add the spaghetti to the boiling liquid and stir right away so the strands don't fuse. Cook for about 7 minutes, stirring often, until al dente. The pasta will look stained purple and the liquid will drop to a syrupy pool.
4. Reserve liquid and drain
Scoop out 1/4 cup of the cooking liquid and set it aside. Drain the spaghetti in a colander. Don't rinse it.
5. Sizzle the garlic
Wipe out the pot or use a large skillet. Heat the olive oil over medium heat, then add the sliced garlic and red pepper flakes. Cook for 2 minutes, stirring now and then, until the garlic smells sweet and turns pale gold.
6. Build the sauce
Pour in the reserved cooking liquid and the reserved 1/4 cup of wine. Bring it to a simmer, then add the drained spaghetti and toss until every strand is coated.
7. Melt in the butter
Drop in the butter and stir until it disappears into the pasta. This is what makes the sauce glossy instead of thin.
8. Finish with cheese and parsley
Season with salt and pepper, then add the parmesan and parsley. Toss to combine. Taste one more time and adjust.
9. Serve
Pile it into warm bowls and top with more parmesan and parsley if you like. A glass of the same wine alongside doesn't hurt.
Variations
Goat cheese version
crumble in about 4 ounces of soft goat cheese in place of the parmesan for a tangier sauce.
Tomato version
stir 1 to 2 tablespoons of tomato paste into the garlic before adding the liquids for a deeper, rounder flavor.
Hearty version
brown sliced jalapeño sausage and toasted walnuts in the skillet first, then set them aside and stir them back in at the end.
How to Store Red Wine Spaghetti
Refrigerator
Keep leftovers in a sealed container for up to 3 days. The pasta soaks up sauce as it sits, so expect it to look dry.
Freezer
Freeze in portions for up to 2 months. The texture softens, so it's better reheated as a quick lunch than served to guests.
Reheating
Warm in a skillet over medium-low heat with a splash of water or wine, tossing until glossy again. A microwave works but dries the edges.
Frequently Asked Questions
Q: What kind of red wine should I use for red wine spaghetti?
A dry, full-bodied red like cabernet sauvignon. It needs enough body to stand up to the garlic and parmesan. Avoid sweet wines and anything heavily oaked, since those flavors concentrate as the liquid cooks down.
Q: Does the alcohol cook off?
Most of it does during the 7-minute boil and the simmer, but not all of it. If you're avoiding alcohol entirely, this isn't the recipe to adapt.
Q: How do I know the pasta is done without a timer?
Bite a strand. It should be tender with a slight firmness at the center and no chalky white core. The pasta also loses its raw, pale look and turns an even deep color.
Q: Can I make this with a gluten-free pasta?
Yes, but watch it closely. Gluten-free spaghetti often cooks faster and turns mushy in the wine, so start checking two minutes early.
Q: Why did my spaghetti clump together?
Either the pot was too small or you didn't stir. Wine-and-water boils up high, so use the biggest pot you own and stir every minute for the first few minutes.
