Before you start
Before starting, ensure your slow cooker is placed on a stable, heat-resistant surface away from any edge. Gather your ingredients and measure them accurately. Check that your slow cooker insert is dry and clean.
Because you are working with raw meat, ensure you have a clean workspace and wash your hands thoroughly after handling the ground beef.
Keeping your ingredients prepared and at hand will make the assembly process smooth and efficient, allowing you to get the meal cooking immediately.
Ingredients at a glance (4)
- 1 lb ground beef
- 12 oz penne pasta, uncooked
- 1 tsp dried oregano
- 2 cups tomato coulis
Instructions
Assembly Phase
- Assemble the ingredientsPlace the raw ground beef into the bottom of the slow cooker, breaking it into smaller pieces if necessary. Add the uncooked penne pasta evenly on top of the beef.Look for Ensure the beef is distributed across the base.Tip Distributing the beef evenly helps it cook consistently throughout the slow cooker.
The ingredients are layered effectively in the slow cooker. The beef is at the bottom to ensure it cooks thoroughly in the hottest part of the vessel, while the pasta and seasonings are arranged on top to absorb the tomato sauce during the cooking cycle.
Cooking Phase
- Season and add sauceSprinkle the dried oregano over the pasta layer. Pour the tomato coulis over the entire mixture, ensuring the pasta is sufficiently coated to allow for even rehydration during cooking.Look for The sauce should cover the pasta.Tip Ensure the pasta is mostly submerged in the tomato coulis to prevent dry edges.
The slow cooker is covered and the heat is set to low. During this time, the ingredients transform as the beef releases its juices and the pasta softens. The kitchen should begin to smell savory and aromatic as the oregano infuses the sauce.
Resting and Serving Phase
- Cook and serveCover and cook on low for 3 hours. Verify the ground beef reaches an internal temperature of 160°F (71°C). Let the dish rest for 5 minutes before serving to allow the sauce to thicken slightly.Look for The pasta is tender and the beef is fully cooked.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip If the pasta seems too firm, stir gently and let it sit for a few extra minutes.
The pasta is tender and the meat is fully cooked. After resting, the sauce should have a glossy, uniform consistency. The dish is now ready to be transferred to plates, providing a warm, comforting meal that is perfectly combined and ready to eat.
Common mistakes
A common mistake is using too little liquid, which can result in dry or crunchy pasta. Ensure the tomato coulis adequately covers the noodles. Another error is over-stirring during the cooking process; keep the lid on as much as possible to maintain the internal temperature.
Avoid adding frozen meat, as this can affect the cooking time and safety; always use properly thawed ground beef. Finally, do not rush the resting period, as this is essential for the sauce to settle and coat the pasta properly.
How to tell it’s done
The dish is done when the penne pasta is tender but still offers a slight bite, and the ground beef is fully cooked through. Use a digital meat thermometer to ensure the ground beef reaches a safe internal temperature of 160°F (71°C).
The sauce should be glossy, thickened, and clinging to the pasta rather than watery. If the pasta is still firm, continue cooking for another 15 minutes, checking periodically to ensure the sauce has not evaporated completely.
