This slow cooker 3-ingredient crushed tomato noodles recipe is my cozy, pantry-stretching version of the rustic, tangy pasta my dad made every April when money was tight but we still wanted something comforting. It leans completely on three basic ingredients—dry pasta, canned crushed tomatoes, and salted butter—to slowly simmer into a thick, rich sauce that hugs every spiral noodle. Everything cooks low and slow in the crockpot, so the tomatoes deepen in flavor, the butter rounds out the tang, and the pasta soaks up all that bright red, chunky goodness. It’s the kind of low-effort, high-payoff meal that feels homemade and nostalgic, even on the busiest weeknight.
Serve these rustic, tangy noodles straight from the slow cooker or divide them into two foil trays like a make-ahead bake. They’re great with a simple green salad, steamed or roasted vegetables, or just a slice of buttered bread to swipe through any extra sauce. A sprinkle of grated cheese, if you have it, is delicious but totally optional. For a fuller meal, pair with leftover roasted chicken or sausage on the side, or pack individual portions into containers for easy grab-and-go lunches throughout the week.
Slow Cooker 3-Ingredient Crushed Tomato NoodlesServings: 6
Ingredients
1 pound (16 ounces) dry spiral pasta (rotini or fusilli)
2 cans (28 ounces each) crushed tomatoes
6 tablespoons salted butter, cut into small pieces
Directions
Lightly grease the inside of a large slow cooker (5–6 quarts) with a small dab of butter or nonstick spray to help prevent sticking.
Pour both cans of crushed tomatoes into the slow cooker. Stir gently to break up any dense spots so the tomatoes are evenly distributed.
Scatter the pieces of salted butter over the top of the crushed tomatoes so they will melt evenly as the mixture heats.
Cover the slow cooker and cook the tomato and butter mixture on HIGH for 1 1/2 to 2 hours, or on LOW for 3 to 4 hours, until the sauce is bubbling around the edges and looks slightly thickened and glossy.
About 30 minutes before you want to eat, stir the sauce well, then add the dry spiral pasta directly to the slow cooker. Use a spoon to press the noodles down into the sauce so they are mostly submerged. It will look thick and crowded at first—that’s what helps the sauce cling to every bite.
Cover and cook on HIGH for 25 to 40 minutes, stirring every 10 minutes or so, until the pasta is tender but not mushy. Each slow cooker runs a little differently, so start checking at the 20–25 minute mark. If the noodles are not yet tender and the sauce seems too thick, you can stir in 1/4 cup hot water at a time, only as needed, to help the pasta finish cooking.
Once the noodles are fully cooked and deeply stained red, give everything a final, thorough stir. The sauce should be thick, chunky, and clinging to every spiral, with very little loose liquid in the bottom.
For an easy, pantry-style presentation and storage, divide the hot pasta evenly between two disposable foil trays, spreading it into an even layer in each. Let cool slightly before covering, or serve immediately straight from the slow cooker or trays while warm and saucy.
Variations & Tips
To keep this true to the three-ingredient spirit, I rely on salted butter to balance the tang of the crushed tomatoes and add a bit of richness, but you can still tweak it while staying simple. If your tomatoes taste especially sharp, stir in an extra tablespoon of butter at the end to mellow the acidity. If you like a looser sauce, add a splash (2–4 tablespoons) of hot water or reserved pasta water while the noodles finish cooking. For a little extra comfort without adding more ingredients to the recipe itself, top individual servings with a sprinkle of any cheese you have on hand, dried herbs, or a pinch of red pepper flakes. This recipe works best with sturdy shapes like rotini, fusilli, or cavatappi; more delicate or tiny shapes can overcook quickly, so check them a bit earlier. For meal prep, portion the cooled pasta into containers and refrigerate for up to 4 days; reheat with a spoonful of water to loosen the sauce. Food safety tips: Do not leave cooked pasta in the slow cooker on the warm setting for more than 2 hours once it’s done; transfer leftovers promptly to shallow containers and refrigerate within 2 hours of cooking. If using foil trays, cool them on a rack before covering so condensation doesn’t drip back onto the pasta and dilute the sauce.
