Step 1: Chop and Prep Your Ingredients

Start by chopping half of a small yellow onion into small, even pieces. You don’t need to break out your food processor—just a sharp knife and a steady hand will do. If onions make you cry like you just watched a sad movie, try refrigerating it for 10 minutes before cutting. Set the chopped onion aside so it’s ready when you need it.

Pro tip: Want to save time? Pre-chop veggies on the weekend and store them in airtight containers. Need an alternative? Swap in frozen chopped onions if you’re in a pinch.

Step 2: Brown the Ground Beef

Heat 2 tablespoons of olive oil in a large, deep, oven-safe skillet over medium-high heat. Add 1 pound of ground beef and cook it for 5 to 7 minutes, stirring and breaking it up with a wooden spoon or spatula. You’ll know it’s ready when the beef is no longer pink and has started to brown nicely.

Once it’s browned, drain off any excess grease. Too much fat left behind can make your dish greasy and heavy, so don’t skip this part. If you’re looking for a leaner option, feel free to use ground turkey or check out our Healthy Hobo Casserole with Ground Beef for a lighter variation.

Step 3: Add the Onion and Cook Until Soft

Toss the chopped onion into the skillet with the browned beef. Sauté it for about 2 to 3 minutes until it softens and turns translucent. Stir frequently so the onion cooks evenly and picks up all those beefy flavors from the bottom of the pan.

This step builds that rich base flavor that makes your One-Pot Taco Spaghetti Bake taste like it simmered for hours—even though it didn’t.

Step 4: Season with Taco Seasoning

Sprinkle in 4 tablespoons of taco seasoning. Stir well, letting the spices coat every bit of beef and onion. You’ll smell the transformation instantly—spicy, smoky, and irresistible.

If you’re using a pre-packaged mix, go for low-sodium to control the saltiness. Making your own? We love a DIY blend with chili powder, cumin, garlic powder, smoked paprika, and a pinch of oregano. You can find more seasoning hacks in our Easy Enchilada Casserole.

Step 5: Pour in Tomatoes and Water

Next, open your can of Rotel tomatoes and do NOT drain the juice. Add the whole 10 oz can into the skillet along with 3 cups of water. Stir everything together until it’s fully combined.

This spicy, tomato-infused broth is what your pasta will soak up—bringing all that taco flavor right into the noodles.

Step 6: Add the Spaghetti (Uncooked!)

Break your 8 oz of spaghetti noodles in half—this helps them fit in the skillet and cook evenly. Carefully add them to the skillet, gently pushing them down into the liquid so they’re mostly submerged.

Cover the skillet with a lid (or foil if yours doesn’t have one) and simmer on medium-low heat for 10 to 12 minutes. Stir occasionally to prevent sticking and help the pasta cook evenly. The noodles should be al dente when done—not mushy, just tender with a little bite.

If you’re craving even more pasta-based comfort food, check out our fan-favorite Creamy Rotel Chicken Spaghetti Casserole—another great one-pot dish.

Step 7: Top with Cheese and Bake

Now the fun part—cheese! Preheat your oven to 350°F (175°C). Once the pasta is cooked and most of the liquid has been absorbed, sprinkle 2/3 cup of shredded cheddar cheese evenly over the top.

Transfer your skillet to the oven and bake uncovered for 15 to 20 minutes, until the cheese is melted, bubbly, and golden. Your kitchen will smell like cheesy Tex-Mex heaven.

Step 8: Garnish and Serve

Carefully remove the skillet from the oven using oven mitts (this baby’s hot!). Let it rest for 5 minutes before digging in. This helps the cheese set and makes it easier to serve.

Finish with a generous sprinkle of chopped fresh cilantro for a pop of color and fresh flavor. If cilantro’s not your thing, green onions or even a dollop of sour cream work great too.

Want something crunchy on the side? Serve it up with tortilla chips or a side of Cowboy Casserole for a Tex-Mex feast.

What to Serve with One-Pot Taco Spaghetti Bake

Truthfully, One-Pot Taco Spaghetti Bake can ride solo and still feel like a complete meal. But if you want to stretch it or round it out, pair it with a simple green salad or some roasted corn on the cob. Tortilla chips and salsa or easy enchilada casserole make for tasty, no-fuss sides that stick with the Tex-Mex theme. Got a hungry crew? Add homemade hobo casserole with ground beef to the table for a two-casserole night (aka the ultimate comfort food buffet).

Key Tips for Making One-Pot Taco Spaghetti Bake

1. Use a deep, oven-safe skillet. This keeps everything in one pan from stovetop to oven. A cast iron or large sauté pan with a lid is perfect.
2. Don’t overcook the noodles. You want al dente, not mushy. Keep an eye while simmering.
3. Stir occasionally. Pasta likes to clump, so a gentle stir every few minutes helps keep things loose and lovely.
4. Choose the right taco seasoning. Go mild for kids or spice it up for heat lovers.
5. Cheese matters. Freshly shredded cheese melts better than pre-shredded (less anti-caking agent = more gooey goodness).

Storage and Reheating Tips for One-Pot Taco Spaghetti Bake

Got leftovers? Lucky you. Let the casserole cool completely, then store it in an airtight container in the fridge for up to 4 days. It reheats beautifully in the microwave or oven. Add a splash of water or broth before reheating to loosen it up. For longer storage, freeze individual portions—just skip the cilantro topping until after reheating. Pro tip: portioning leftovers into lunch containers now means you’ve already won at tomorrow.

FAQs

Can I make this with chicken or turkey?
Absolutely. Ground turkey or shredded rotisserie chicken both work great.

What if I don’t have Rotel?
Use canned diced tomatoes and add a dash of green chilies or hot sauce for heat.

Can I make this dairy-free?
Skip the cheese or use a dairy-free alternative. Add avocado on top for creaminess.

Can I use gluten-free pasta?
Sure, just keep an eye on cook time. Some gluten-free noodles cook faster and may break more easily.
