Grab a large skillet or Dutch oven and set it over medium-high heat. Add your ground beef and break it up with a spoon. Let it brown beautifully, really getting some nice color on it—that's where the flavor lives, hon! Drain off any excess grease; honestly, I usually just tilt the pan and scoop it out with a spoon, trying not to make too much of a mess (which I usually do). Toss in your chopped onion, sliced carrots, and a pinch of salt and pepper. Let them soften up for about 5-7 minutes, stirring occasionally, until the onions are translucent and smelling sweet. This is where the kitchen starts to smell absolutely divine, a prelude to the good stuff coming!

Now, clear a little space in the center of your pan and add the minced garlic and tomato paste. Let them cook for about a minute, stirring them directly into the hot pan bottom. You want to toast that tomato paste a bit; it deepens its flavor immensely. I learned this trick the hard way, by just dumping it in and losing out on that rich umami. Stir everything together with the beef and veggies, making sure that fragrant garlic and concentrated tomato get mixed throughout. Oh, and don't forget the dried thyme now; it needs a moment to bloom in the heat.

Pour in your beef broth and Worcestershire sauce. Give it a good stir, scraping up any delicious browned bits from the bottom of the pan – that's called fond, and it's pure flavor gold! Bring the mixture to a gentle simmer. This step is where all those individual ingredients start to meld into a cohesive, savory sauce. Let it bubble away for about 5 minutes, allowing the flavors to really get acquainted. You'll notice the liquid reducing slightly, becoming a lovely, rich base for your casserole. Taste it here, add more salt or pepper if it needs a little kick!

Carefully add your diced potatoes to the skillet. Give everything a good stir to make sure the potatoes are nestled down into that delicious sauce. You want them mostly submerged so they can cook evenly and absorb all that flavor. Cover the skillet, reduce the heat to medium-low, and let it simmer for about 20-25 minutes, or until the potatoes are tender when pierced with a fork. Honestly, I always check a few times, because nothing’s worse than crunchy potatoes in a casserole! If the sauce seems too thick, a splash more broth won't hurt. If it's too thin, a little longer uncovered will help.

Once your potatoes are perfectly tender, stir in the frozen peas. They'll warm through quickly in the residual heat. Then, sprinkle that glorious shredded cheddar cheese evenly over the top of the casserole. This is the moment where it starts to look like the comforting dish you’ve been dreaming of. I usually go a little heavy on the cheese, because, well, cheese! You can't really go wrong here. Just make sure it's spread out so every bite gets a cheesy topping.

Pop the skillet back onto the stove, or if your pan is oven-safe, into a preheated oven at 375°F (190°C) for 5-10 minutes, just until the cheese is beautifully melted and bubbly. If you're using the stove, cover it again for a few minutes. You want that golden, gooey top! Once it's all melty and irresistible, remove it from the heat. Let it rest for a few minutes before serving – this lets the flavors settle and prevents you from burning your tongue with impatience (speaking from experience!). Garnish with fresh chopped parsley for a final flourish. Dig in!
