Spaghetti & Spinach With Sun-dried Tomato Cream Sauce is a creamy pasta dinner made with whole-wheat spaghetti, tender spinach, and sweet oil-packed sun-dried tomatoes. It gives you a cozy bowl of pasta with a lighter pantry-friendly sauce that comes together from broth, sour cream, Parmesan, and a little butter instead of a heavy cream base. I like this recipe for weeknights because the sauce cooks in the same time it takes to boil the pasta, and the spinach folds in without extra pans. The onion and garlic make the sauce savory, while crushed red pepper adds just enough warmth. It is flexible enough for a meatless dinner with vegetable broth or a heartier family meal with chicken broth on busy nights.

Why You’ll Love This Spaghetti & Spinach With Sun-dried Tomato Cream Sauce

This pasta is creamy, colorful, and practical enough for a weeknight dinner. Here’s why:

• Creamy without heavy cream: Sour cream, broth, Parmesan, and butter make a smooth sauce that feels rich but stays grocery-store friendly.
• Vegetables built in: Baby spinach wilts right into the hot pasta, adding color and tenderness without a separate side dish.
• Big pantry flavor: Oil-packed sun-dried tomatoes bring a deep sweet-savory taste that makes the sauce feel special with only a few extras.
• Flexible broth option: Use vegetable broth for a meatless pasta dinner or chicken broth for a slightly heartier family-style plate.
• Weeknight timing: The sauce cooks while the spaghetti boils, so the whole pan comes together without a long prep list.

Ingredients You’ll Need

• Baby Spinach (5 ounces): Coarsely chop it so it folds evenly through the spaghetti and softens quickly from the heat of the sauce.
• Whole-Wheat Spaghetti (8 ounces): This gives the dish a nutty bite and holds up nicely under the creamy tomato sauce.
• Sun-Dried Tomato Oil (1 tablespoon): Use oil from the jar to start the onion and garlic with extra tomato flavor from the first step.
• Oil-Packed Sun-Dried Tomatoes (1/2 cup): Slivered tomatoes add chewy texture, savory sweetness, and the main flavor base for this pasta.
• Onion (1/2 cup): Thinly sliced onion softens into the sauce and helps balance the sharpness of the tomatoes and garlic.
• Garlic (3 cloves): Fresh minced garlic gives the cream sauce a warm savory backbone without needing many seasonings.
• Crushed Red Pepper (1/4 teaspoon): This adds mild heat. Use less for a gentler family dinner or a bit more for a warmer finish.
• Salt and Ground Pepper (1/4 teaspoon each): These season the sauce simply while letting the Parmesan and tomatoes stay noticeable.
• Low-Sodium Broth (1 cup): Vegetable or chicken broth loosens the sauce and helps the sour cream blend smoothly around the pasta.
• Sour Cream (1/2 cup): Stir it in off the strongest heat so the sauce turns creamy without separating.
• Parmesan Cheese (1/4 cup): Grated Parmesan adds salty depth and helps the sauce cling to the spaghetti strands.
• Unsalted Butter (1 tablespoon): A small finish of butter rounds out the sauce and gives the pasta a softer glossy coating.

Before You Start

• Save Pasta Water: Scoop out a little cooking water before draining in case the sauce needs loosening at the end.
• Lower the Heat: Sour cream blends best when the pan is warm but not boiling hard.
• Use a Deep Skillet: Choose a pan large enough to toss spaghetti, spinach, and sauce without spilling.
• Chop Spinach First: Smaller pieces wilt evenly and make the pasta easier to twirl and serve.

How to Make Spaghetti & Spinach With Sun-dried Tomato Cream Sauce

• Step 1 – Boil Spaghetti: Cook spaghetti in salted boiling water until just tender, then reserve 1/2 cup pasta water and drain.
• Step 2 – Start Aromatics: Heat sun-dried tomato oil in a deep skillet, then cook onion until softened and lightly golden.
• Step 3 – Add Tomato Base: Stir in sun-dried tomatoes, garlic, crushed red pepper, salt, and pepper until fragrant.
• Step 4 – Simmer Sauce: Pour in broth and simmer for a few minutes so the tomatoes soften and season the liquid.
• Step 5 – Make It Creamy: Reduce heat to low, stir in sour cream and Parmesan, then add butter until melted.
• Step 6 – Toss Pasta: Add drained spaghetti and spinach, tossing until the greens wilt and the sauce coats every strand.
• Step 7 – Adjust and Serve: Loosen with reserved pasta water if needed, taste for seasoning, and serve warm with extra Parmesan.

How to Know When Spaghetti & Spinach With Sun-dried Tomato Cream Sauce Is Done

• Pasta Texture: The spaghetti should be tender with a slight bite, not soft or breaking apart.
• Sauce Consistency: The sauce should coat the pasta in a creamy layer without looking watery or separated.
• Spinach Cue: The spinach should be wilted, bright green, and evenly mixed through the noodles.
• Final Taste: The tomatoes should taste savory and balanced, with enough salt and Parmesan to bring the sauce together.

Tips to Make It Easier

• Use the Jar Oil: I use oil from the sun-dried tomato jar because it adds flavor before any broth goes in.
• Keep Heat Gentle: Avoid boiling after adding sour cream so the sauce stays smooth and evenly blended.
• Slice Onion Thinly: Thin onion cooks faster and disappears into the sauce instead of staying sharp.
• Loosen as Needed: I keep reserved pasta water nearby because whole-wheat spaghetti can soak up sauce quickly.
• Grate Fresh Parmesan: Freshly grated cheese melts more smoothly than pre-shredded cheese with anti-caking ingredients.
• Taste at the End: Sun-dried tomatoes and Parmesan vary in saltiness, so final seasoning matters more than early seasoning.

How to Store and Reheat

• Fridge: Store cooled leftovers in an airtight container for 3 to 4 days.
• Freezer: Freezing is not ideal because sour cream sauce can separate, but it can be frozen for up to 1 month.
• Reheat: Warm gently in a skillet with a splash of broth or water until creamy again.
• Microwave: Heat in short bursts, stirring between each round so the sauce warms evenly.
• Food Safety: Refrigerate leftovers within 2 hours and reheat until steaming hot before serving.

Easy Swaps & Add-Ins

• Pasta Shape: Use linguine, fettuccine, penne, or spiral pasta if that is what you have on hand.
• Greens: Swap spinach for chopped kale or baby arugula, adding a little extra simmer time for sturdier greens.
• Protein: Add cooked chicken, white beans, or shrimp to make the pasta more filling.
• Cheese: Try Pecorino Romano for a sharper salty finish in place of Parmesan.
• Herbs: Add basil, parsley, or a little oregano for a fresher finish at the table.
• Cream Base: Greek yogurt can work in place of sour cream if stirred in gently off the heat.

What to Serve With Spaghetti & Spinach With Sun-dried Tomato Cream Sauce

• Garlic Bread: A crisp slice is useful for catching any creamy tomato sauce left on the plate.
• Green Salad: A lemony salad keeps the meal fresh and balances the richness of the sauce.
• Roasted Broccoli: The lightly crisp edges pair well with the creamy pasta and sweet tomatoes.
• Grilled Chicken: Serve sliced chicken on top when you want a heartier pasta dinner.
• Tomato Cucumber Salad: Cool vegetables bring a bright contrast to the warm sauce.
• Simple Soup: A small bowl of vegetable soup turns the pasta into a cozy dinner spread.
