How to Make Pantry Spaghetti with Tomato Sauce

1. Cook the pasta: Bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente. Reserve 1/2 cup of pasta water, then drain well.
2. Make the sauce: While the pasta cooks, heat olive oil in a separate skillet or saucepan over medium heat. If using fresh garlic, add it and sauté for 1 minute until fragrant. If using garlic powder, skip this step.
3. Add tomatoes and seasonings: Pour in the crushed tomatoes, oregano, basil, smoked paprika, sugar, salt, and pepper. If using garlic powder, add it now. Stir well and simmer for 8-10 minutes until the sauce thickens slightly.
4. Combine and serve: Add the drained spaghetti to the sauce and toss to coat. If the sauce is too thick, add a splash of the reserved pasta water to reach your desired consistency. Serve hot with a sprinkle of Parmesan cheese if available.

Tips for the Best RV Spaghetti

• Salt the pasta water: This is your only chance to season the pasta itself. Use about 1 tablespoon of salt per gallon of water.
• Add smoky flavor: A pinch of smoked paprika adds a lovely charred, campfire nuance without a grill.
• Use pasta water: The starchy water helps the sauce cling to the spaghetti and creates a silky texture.
• Save leftovers: This sauce freezes beautifully, so you can make a double batch and have a meal ready for another night.

5 Delicious Variations to Try

• Spicy Arrabbiata: Add 1/2 teaspoon of red pepper flakes along with the tomatoes for a fiery kick.
• Vegetable-Packed Sauce: Stir in a can of drained mushrooms, olives, or artichoke hearts along with the sauce.
• Meaty Version: Brown a pouch of canned chicken or a can of drained tuna, then stir it into the sauce at the end.
• Cheesy Baked Spaghetti: Transfer the sauced pasta to a small baking dish, top with cheese, and broil until bubbly.
• Herby Pesto Twist: Stir in a spoonful of jarred pesto for a fresh, herby finish.

Storage and Reheating Instructions

Store leftover spaghetti in an airtight container in the RV refrigerator for up to 4 days. To reheat, warm in a skillet over medium-low heat with a splash of water or broth to revive the sauce. You can also microwave individual portions with a damp paper towel over the top to prevent drying. This sauce also freezes well for up to 3 months.

Frequently Asked Questions (FAQ)

Can I use fresh tomatoes instead of canned?

Yes! Use 2 lbs of ripe Roma tomatoes, chopped. You may need to simmer a bit longer to break them down and develop the sauce.

Can I use another type of pasta?

Absolutely! Penne, shells, rotini, or any short pasta works beautifully. Adjust cooking times according to the package.

How do I add smoky flavor without a grill?

Smoked paprika is the key. A dash of liquid smoke or a spoonful of chipotle salsa also adds a wonderful BBQ-like depth.

Can I make this sauce in a slow cooker?

Yes! Combine all sauce ingredients in a slow cooker and cook on LOW for 2-3 hours. Cook the pasta separately and combine before serving.

What can I serve with spaghetti?

Garlic bread, a simple side salad, or steamed vegetables all pair beautifully. For a complete meal, add canned chicken or tuna.
