Before you start
Before beginning, ensure all your ingredients are measured and ready. Mince the garlic finely to ensure it distributes evenly throughout the sauce during the long cooking process.
If your cherry tomatoes are large, you can halve them to help them release their juices faster, though whole tomatoes will also burst naturally during the simmer. Have your pasta pot ready with plenty of water and salt, and clear your workspace so you can easily manage the assembly of the sauce in the slow cooker bowl.

Instructions
Sauce Assembly
- Combine Sauce IngredientsAdd the crushed tomatoes, cherry tomatoes, pitted Kalamata olives, capers, minced garlic, anchovy fillets, and olive oil into your slow cooker bowl. Stir gently to combine all the aromatic ingredients evenly before starting the cook cycle.Look for Ensure the anchovies are distributed throughout the mixture so they melt into the sauce during the long simmer.Tip To make cleanup easier, use a slow cooker liner before adding the ingredients.
At this stage, the slow cooker bowl should be filled with vibrant ingredients. The crushed tomatoes provide the base, while the cherry tomatoes, olives, and aromatics are layered in. Everything should look colorful and fresh, with the anchovies tucked into the mixture to ensure they melt during the heating process. Check that your slow cooker is clean and the lid fits tightly before turning it on to begin the slow simmer.
Slow Simmering
- Slow Cook the SauceCover the slow cooker with its lid and set to low. Simmer for three hours. The tomatoes will burst and release their juices, while the olives and garlic meld with the anchovies to create a thick, savory jam-like consistency.Look for The sauce is ready when the cherry tomatoes have collapsed and the liquid has reduced into a thick, glossy, and fragrant sauce.Tip Avoid lifting the lid frequently, as this releases heat and extends the cooking time significantly.
The sauce is simmering gently. You will notice the cherry tomatoes have begun to soften and release their juices, mingling with the oil and aromatics. The kitchen should begin to smell savory and briny as the flavors meld.
Occasionally check to ensure the liquid is not evaporating too quickly, although the lid should keep the moisture trapped. The sauce is evolving from individual components into a unified, jammy, and fragrant Italian-style dressing.
Final Toss and Serve
- Combine and ServeCook the spaghetti in a large pot of boiling salted water until al dente. Drain well. Toss the hot cooked pasta directly into the slow cooker with the sauce and stir in the fresh chopped parsley until every strand is coated. Garnish with toasted garlic breadcrumbs and fresh basil.Look for The pasta should be thoroughly coated in the sauce and appear glossy and vibrant before serving.Tip Reserve a small splash of the pasta cooking water to loosen the sauce if it appears too thick.
The pasta is cooked, drained, and ready to meet the sauce. Once tossed together, the spaghetti should be coated in a glossy, crimson sauce that clings to the strands. The fresh parsley should be distributed evenly, adding a bright green contrast. The final dish should be steaming hot, aromatic, and ready to be garnished with the crunchy breadcrumbs and fresh basil leaves for a beautiful, appetizing presentation.
Common mistakes
A common mistake is adding the pasta to the slow cooker to cook, which will result in mushy, overcooked noodles. Always cook your pasta separately in boiling water until al dente and combine it with the sauce right before serving.
Another error is neglecting to taste the sauce before serving; because capers and olives vary in saltiness, you should always check the seasoning and adjust with a pinch of salt or a drizzle of olive oil if needed to balance the bold flavors.
How to tell it’s done
The sauce is done when the cherry tomatoes have completely collapsed and the mixture has thickened into a rich, glossy consistency. The garlic and anchovies should have fully integrated into the sauce, leaving no distinct pieces behind.
The sauce should smell deeply aromatic, savory, and slightly sweet from the reduced tomatoes. If you find the sauce is too thick, simply stir in a small amount of the starchy pasta water until it reaches your desired consistency for coating the noodles.
